Release v1.11.3

Currently numbers are stripped not just after the color control code (\x03) but also after other formatting such as bold (\x02) and italic (\x1D), which is both unnecessary and leads to missing text from irc. This fixes that by only stripping numbers after the color control code.

-Simple bridge between mattermost, IRC, XMPP, Gitter and Slack
-
-* Relays public channel messages between mattermost, IRC, XMPP, Gitter and Slack. Pick and mix.
-* Supports multiple channels.
-* Matterbridge can also work with private groups on your mattermost.
-
-Look at [matterbridge.conf.sample] (https://github.com/42wim/matterbridge/blob/master/matterbridge.conf.sample) for documentation and an example.
-
-## Changelog
-Since v0.6.1 support for XMPP, Gitter and Slack is added. More details in [changelog.md] (https://github.com/42wim/matterbridge/blob/master/changelog.md)
-
-## Requirements:
-Accounts to one of the supported bridges
-* [Mattermost] (https://github.com/mattermost/platform/)
-* [IRC] (http://www.mirc.com/servers.html)
-* [XMPP] (https://jabber.org)
-* [Gitter] (https://gitter.im)
-* [Slack] (https://www.slack.com)
-
-## binaries
-Binaries can be found [here] (https://github.com/42wim/matterbridge/releases/)
-* For use with mattermost 3.3.0+ [v0.6.1](https://github.com/42wim/matterircd/releases/tag/v0.6.1)
-* For use with mattermost 3.0.0-3.2.0 [v0.5.0](https://github.com/42wim/matterircd/releases/tag/v0.5.0)
-
-
-## Docker
-Create your matterbridge.conf file locally eg in ```/tmp/matterbridge.conf```
-
-```
-docker run -ti -v /tmp/matterbridge.conf:/matterbridge.conf 42wim/matterbridge:0.6.1
-```
-
-## Compatibility
-### Mattermost 
-* Matterbridge v0.6.1 works with mattermost 3.3.0 and higher [3.3.0 release](https://github.com/mattermost/platform/releases/tag/v3.3.0)
-* Matterbridge v0.5.0 works with mattermost 3.0.0 - 3.2.0 [3.2.0 release](https://github.com/mattermost/platform/releases/tag/v3.2.0)
-
-
-#### Webhooks version
-* Configured incoming/outgoing [webhooks](https://www.mattermost.org/webhooks/) on your mattermost instance.
-
-#### Plus (API) version
-* A dedicated user(bot) on your mattermost instance.
-
-
-## building
-Go 1.6+ is required. Make sure you have [Go](https://golang.org/doc/install) properly installed, including setting up your [GOPATH] (https://golang.org/doc/code.html#GOPATH)
-
-```
-cd $GOPATH
-go get github.com/42wim/matterbridge
-```
-
-You should now have matterbridge binary in the bin directory:
-
-```
-$ ls bin/
-matterbridge
-```
-
-## running
-1) Copy the matterbridge.conf.sample to matterbridge.conf in the same directory as the matterbridge binary.  
-2) Edit matterbridge.conf with the settings for your environment. See below for more config information.  
-3) Now you can run matterbridge. 
-
-```
-Usage of ./matterbridge:
-  -conf string
-        config file (default "matterbridge.conf")
-  -debug
-        enable debug
-  -plus
-        running using API instead of webhooks (deprecated, set Plus flag in [general] config)
-  -version
-        show version
-```
-
-## config
-### matterbridge
-matterbridge looks for matterbridge.conf in current directory. (use -conf to specify another file)
-
-Look at [matterbridge.conf.sample] (https://github.com/42wim/matterbridge/blob/master/matterbridge.conf.sample) for an example.
-
-### mattermost
-#### webhooks version
-You'll have to configure the incoming and outgoing webhooks. 
-
-* incoming webhooks
-Go to "account settings" - integrations - "incoming webhooks".  
-Choose a channel at "Add a new incoming webhook", this will create a webhook URL right below.  
-This URL should be set in the matterbridge.conf in the [mattermost] section (see above)  
-
-* outgoing webhooks
-Go to "account settings" - integrations - "outgoing webhooks".  
-Choose a channel (the same as the one from incoming webhooks) and fill in the address and port of the server matterbridge will run on.  
-
-e.g. http://192.168.1.1:9999 (192.168.1.1:9999 is the BindAddress specified in [mattermost] section of matterbridge.conf)
-
-#### plus version
-You'll have to create a new dedicated user on your mattermost instance.
-Specify the login and password in [mattermost] section of matterbridge.conf
-
-## FAQ
-Please look at [matterbridge.conf.sample] (https://github.com/42wim/matterbridge/blob/master/matterbridge.conf.sample) for more information first. 
-### Mattermost doesn't show the IRC nicks
-If you're running the webhooks version, this can be fixed by either:
-* enabling "override usernames". See [mattermost documentation](http://docs.mattermost.com/developer/webhooks-incoming.html#enabling-incoming-webhooks)
-* setting ```PrefixMessagesWithNick``` to ```true``` in ```mattermost``` section of your matterbridge.conf.
-
-If you're running the plus version you'll need to:
-* setting ```PrefixMessagesWithNick``` to ```true``` in ```mattermost``` section of your matterbridge.conf.
-
-Also look at the ```RemoteNickFormat``` setting.

+  * BindAddress => WebhookBindAddress
+  * UseAPI => removed 
+  This change allows you to specify a WebhookURL and a token (slack,discord), so that
+  messages will be sent with the webhook, but received via the token (API)
+  If you have not specified WebhookURL and WebhookBindAddress the API (login or token) 
+  will be used automatically. (no need for UseAPI)
+
+## New features
+* steam: New protocol support added (http://store.steampowered.com/)
+* discord: WebhookURL posting support added (thanks @saury07) #204
+  Discord API does not allow to change the name of the user posting, but webhooks does.
+
+## Bugfix
+* general: samechannelgateway now relays messages correct again #207
+* slack: Remove label from URLs (slack). #205
+
+# v0.15.0
+## New features
+* general: add option IgnoreMessages for all protocols (see mattebridge.toml.sample)
+  Messages matching these regexp will be ignored and not sent to other bridges
+  e.g. IgnoreMessages="^~~ badword"
+* telegram: add support for sticker/video/photo/document #184
+
+## Changes
+* api: add userid to each message #200
+
+## Bugfix
+* discord: fix crash in memberupdate #198
+* mattermost: Fix incorrect behaviour of EditDisable (mattermost). Fixes #197 
+* irc: Do not relay join/part of ourselves (irc). Closes #190 
+* irc: make reconnections more robust. #153
+* gitter: update library, fixes possible crash
+
 # v0.14.0
 ## New features
 * api: add token authentication

+- [Rooms](#rooms)
+- [Messages](#messages)
+- [Stream](#stream)
+- [Faye (Experimental)](#faye-experimental)
+- [Debug](#debug)
+- [App Engine](#app-engine)
+
+##### Initialize
+``` Go
+api := gitter.New("YOUR_ACCESS_TOKEN")
+```
+
+##### Users
+
+- Get current user
+
+	``` Go
+	user, err := api.GetUser()
+	```
+
+##### Rooms
+
+- Get all rooms
+	``` Go
+	rooms, err := api.GetRooms()
+	```
+
+- Get room by id
+	``` Go
+	room, err := api.GetRoom("roomID")
+	```
+
+- Get rooms of some user
+	``` Go
+	rooms, err := api.GetRooms("userID")
+	```
+
+- Join room
+	``` Go
+	room, err := api.JoinRoom("roomID", "userID")
+	```
+	
+- Leave room
+	``` Go
+	room, err := api.LeaveRoom("roomID", "userID")
+	```
+
+- Get room id
+	``` Go
+	id, err := api.GetRoomId("room/uri")
+	```
+
+- Search gitter rooms
+	``` Go
+	rooms, err := api.SearchRooms("search/string")
+	```
+##### Messages
+
+- Get messages of room
+	``` Go
+	messages, err := api.GetMessages("roomID", nil)
+	```
+
+- Get one message
+	``` Go
+	message, err := api.GetMessage("roomID", "messageID")
+	```
+
+- Send message
+	``` Go
+	err := api.SendMessage("roomID", "free chat text")
+	```
+
+##### Stream
+
+Create stream to the room and start listening to incoming messages
+
+``` Go
+stream := api.Stream(room.Id)
+go api.Listen(stream)
+
+for {
+    event := <-stream.Event
+    switch ev := event.Data.(type) {
+    case *gitter.MessageReceived:
+        fmt.Println(ev.Message.From.Username + ": " + ev.Message.Text)
+    case *gitter.GitterConnectionClosed:
+        // connection was closed
+    }
+}
+```
+
+Close stream connection
+
+``` Go
+stream.Close()
+```
+
+##### Faye (Experimental)
+
+``` Go
+faye := api.Faye(room.ID)
+go faye.Listen()
+
+for {
+    event := <-faye.Event
+    switch ev := event.Data.(type) {
+    case *gitter.MessageReceived:
+        fmt.Println(ev.Message.From.Username + ": " + ev.Message.Text)
+    case *gitter.GitterConnectionClosed: //this one is never called in Faye
+        // connection was closed
+    }
+}
+```
+
+##### Debug
+
+You can print the internal errors by enabling debug to true
+
+``` Go
+api.SetDebug(true, nil)
+```
+
+You can also define your own `io.Writer` in case you want to persist the logs somewhere.
+For example keeping the errors on file
+
+``` Go
+logFile, err := os.Create("gitter.log")
+api.SetDebug(true, logFile)
+```
+
+##### App Engine
+
+Initialize app engine client and continue as usual
+
+``` Go
+c := appengine.NewContext(r)
+client := urlfetch.Client(c)
+
+api := gitter.New("YOUR_ACCESS_TOKEN")
+api.SetClient(client)
+```

+This package passes all tests in
+[toml-test](https://github.com/BurntSushi/toml-test) for both the decoder
+and the encoder.
+
+### Examples
+
+This package works similarly to how the Go standard library handles `XML`
+and `JSON`. Namely, data is loaded into Go values via reflection.
+
+For the simplest example, consider some TOML file as just a list of keys
+and values:
+
+```toml
+Age = 25
+Cats = [ "Cauchy", "Plato" ]
+Pi = 3.14
+Perfection = [ 6, 28, 496, 8128 ]
+DOB = 1987-07-05T05:45:00Z
+```
+
+Which could be defined in Go as:
+
+```go
+type Config struct {
+  Age int
+  Cats []string
+  Pi float64
+  Perfection []int
+  DOB time.Time // requires `import time`
+}
+```
+
+And then decoded with:
+
+```go
+var conf Config
+if _, err := toml.Decode(tomlData, &conf); err != nil {
+  // handle error
+}
+```
+
+You can also use struct tags if your struct field name doesn't map to a TOML
+key value directly:
+
+```toml
+some_key_NAME = "wat"
+```
+
+```go
+type TOML struct {
+  ObscureKey string `toml:"some_key_NAME"`
+}
+```
+
+### Using the `encoding.TextUnmarshaler` interface
+
+Here's an example that automatically parses duration strings into
+`time.Duration` values:
+
+```toml
+[[song]]
+name = "Thunder Road"
+duration = "4m49s"
+
+[[song]]
+name = "Stairway to Heaven"
+duration = "8m03s"
+```
+
+Which can be decoded with:
+
+```go
+type song struct {
+  Name     string
+  Duration duration
+}
+type songs struct {
+  Song []song
+}
+var favorites songs
+if _, err := toml.Decode(blob, &favorites); err != nil {
+  log.Fatal(err)
+}
+
+for _, s := range favorites.Song {
+  fmt.Printf("%s (%s)\n", s.Name, s.Duration)
+}
+```
+
+And you'll also need a `duration` type that satisfies the
+`encoding.TextUnmarshaler` interface:
+
+```go
+type duration struct {
+	time.Duration
+}
+
+func (d *duration) UnmarshalText(text []byte) error {
+	var err error
+	d.Duration, err = time.ParseDuration(string(text))
+	return err
+}
+```
+
+### More complex usage
+
+Here's an example of how to load the example from the official spec page:
+
+```toml
+# This is a TOML document. Boom.
+
+title = "TOML Example"
+
+[owner]
+name = "Tom Preston-Werner"
+organization = "GitHub"
+bio = "GitHub Cofounder & CEO\nLikes tater tots and beer."
+dob = 1979-05-27T07:32:00Z # First class dates? Why not?
+
+[database]
+server = "192.168.1.1"
+ports = [ 8001, 8001, 8002 ]
+connection_max = 5000
+enabled = true
+
+[servers]
+
+  # You can indent as you please. Tabs or spaces. TOML don't care.
+  [servers.alpha]
+  ip = "10.0.0.1"
+  dc = "eqdc10"
+
+  [servers.beta]
+  ip = "10.0.0.2"
+  dc = "eqdc10"
+
+[clients]
+data = [ ["gamma", "delta"], [1, 2] ] # just an update to make sure parsers support it
+
+# Line breaks are OK when inside arrays
+hosts = [
+  "alpha",
+  "omega"
+]
+```
+
+And the corresponding Go types are:
+
+```go
+type tomlConfig struct {
+	Title string
+	Owner ownerInfo
+	DB database `toml:"database"`
+	Servers map[string]server
+	Clients clients
+}
+
+type ownerInfo struct {
+	Name string
+	Org string `toml:"organization"`
+	Bio string
+	DOB time.Time
+}
+
+type database struct {
+	Server string
+	Ports []int
+	ConnMax int `toml:"connection_max"`
+	Enabled bool
+}
+
+type server struct {
+	IP string
+	DC string
+}
+
+type clients struct {
+	Data [][]interface{}
+	Hosts []string
+}
+```
+
+Note that a case insensitive match will be tried if an exact match can't be
+found.
+
+A working example of the above can be found in `_examples/example.{go,toml}`.

+# Steam for Go
+
+This library implements Steam's protocol to allow automation of different actions on Steam without running an actual Steam client. It is based on [SteamKit2](https://github.com/SteamRE/SteamKit), a .NET library.
+
+In addition, it contains APIs to Steam Community features, like trade offers and inventories.
+
+Some of the currently implemented features:
+
+  * Trading and trade offers, including inventories and notifications
+  * Friend and group management
+  * Chatting with friends
+  * Persona states (online, offline, looking to trade, etc.)
+  * SteamGuard with two-factor authentication
+  * Team Fortress 2: Crafting, moving, naming and deleting items
+
+If this is useful to you, there's also the [go-steamapi](https://github.com/Philipp15b/go-steamapi) package that wraps some of the official Steam Web API's types.
+
+## Installation
+
+    go get github.com/Philipp15b/go-steam
+
+## Usage
+
+You can view the documentation with the [`godoc`](http://golang.org/cmd/godoc) tool or
+[online on godoc.org](http://godoc.org/github.com/Philipp15b/go-steam).
+
+You should also take a look at the following sub-packages:
+
+  * [`gsbot`](http://godoc.org/github.com/Philipp15b/go-steam/gsbot) utilites that make writing bots easier
+  * [example bot](http://godoc.org/github.com/Philipp15b/go-steam/gsbot/gsbot) and [its source code](https://github.com/Philipp15b/go-steam/blob/master/gsbot/gsbot/gsbot.go)
+  * [`trade`](http://godoc.org/github.com/Philipp15b/go-steam/trade) for trading
+  * [`tradeoffer`](http://godoc.org/github.com/Philipp15b/go-steam/tradeoffer) for trade offers
+  * [`economy/inventory`](http://godoc.org/github.com/Philipp15b/go-steam/economy/inventory) for inventories
+  * [`tf2`](http://godoc.org/github.com/Philipp15b/go-steam/tf2) for Team Fortress 2 related things
+
+## Working with go-steam
+
+Whether you want to develop your own Steam bot or directly work on go-steam itself, there are are few things to know.
+
+ * If something is not working, check first if the same operation works (under the same conditions!) in the Steam client on that account. Maybe there's something go-steam doesn't handle correctly or you're missing a warning that's not obviously shown in go-steam. This is particularly important when working with trading since there are [restrictions](https://support.steampowered.com/kb_article.php?ref=1047-edfm-2932), for example newly authorized devices will not be able to trade for seven days.
+ * Since Steam does not maintain a public API for most of the things go-steam implements, you can expect that sometimes things break randomly. Especially the `trade` and `tradeoffer` packages have been affected in the past.
+ * Always gather as much information as possible. When you file an issue, be as precise and complete as you can. This makes debugging way easier.
+ * If you haven't noticed yet, expect to find lots of things out yourself. Debugging can be complicated and Steam's internals are too.
+ * Sometimes things break and other [SteamKit ports](https://github.com/SteamRE/SteamKit/wiki/Ports) are fixed already. Maybe take a look what people are saying over there? There's also the [SteamKit IRC channel](https://github.com/SteamRE/SteamKit/wiki#contact).
+
+## Updating go-steam to a new SteamKit version
+
+To update go-steam to a new version of SteamKit, do the following:
+
+	go get github.com/golang/protobuf/protoc-gen-go/
+    git submodule init && git submodule update
+    cd generator
+    go run generator.go clean proto steamlang
+
+Make sure that `$GOPATH/bin` / `protoc-gen-go` is in your `$PATH`. You'll also need [`protoc`](https://developers.google.com/protocol-buffers/docs/downloads), the protocol buffer compiler. At the moment, we use Protocol Buffers 2.6.1 with `proco-gen-go`-[2402d76](https://github.com/golang/protobuf/tree/2402d76f3d41f928c7902a765dfc872356dd3aad).
+
+To compile the Steam Language files, you also need the [.NET Framework](https://www.microsoft.com/net/downloads)
+on Windows or [mono](http://www.go-mono.com/mono-downloads/download.html) on other operating systems.
+
+Apply the protocol changes where necessary.

+This package allows you to automate actions on Valve's Steam network. It is a Go port of SteamKit.
+
+To login, you'll have to create a new Client first. Then connect to the Steam network
+and wait for a ConnectedCallback. Then you may call the Login method in the Auth module
+with your login information. This is covered in more detail in the method's documentation. After you've
+received the LoggedOnEvent, you should set your persona state to online to receive friend lists etc.
+
+Example code
+
+You can also find a running example in the `gsbot` package.

+				log.Print(e)
+			case error:
+				log.Print(e)
+			}
+		}

+Events
+
+go-steam emits events that can be read via Client.Events(). Although the channel has the type interface{},
