Release v1.8.0

An extra avatarMap (cache) is created for mattermost and telegram.
If MediaServerUpload is configured, the avatar images of users are downloaded the first time a
user sends a message.
If this download succeeds a message with EVENT_AVATAR_DOWNLOAD is sent to the originating protocol.
This message also contains a SHA field (in msg.Extra["file"]), if this is not empty, the sha will
be added to the avatarMap. (so we now have a userid-sha cache)

Next time this user sends a message, the MediaServerUpload/sha/userid.png URL will be used as the
avatar field.

 # Features
-* Relays public channel messages between multiple mattermost, IRC, XMPP, Gitter, Slack, Discord, Telegram, Rocket.Chat, Hipchat (via xmpp), Matrix and Steam. 
-  Pick and mix.
-* Support private groups on your mattermost/slack.
-* Allow for bridging the same bridges, which means you can eg bridge between multiple mattermosts.
-* The bridge is now a gateway which has support multiple in and out bridges. (and supports multiple gateways).
-* Edits and delete messages across bridges that support it (mattermost,slack,discord,gitter,telegram)
-* REST API to read/post messages to bridges (WIP).
+* [Support bridging between any protocols](https://github.com/42wim/matterbridge/wiki/Features#support-bridging-between-any-protocols)
+* [Support multiple gateways(bridges) for your protocols](https://github.com/42wim/matterbridge/wiki/Features#support-multiple-gatewaysbridges-for-your-protocols)
+* [Message edits and deletes](https://github.com/42wim/matterbridge/wiki/Features#message-edits-and-deletes)
+* [Attachment / files handling](https://github.com/42wim/matterbridge/wiki/Features#attachment--files-handling)

+## API
+The API is very basic at the moment and rather undocumented.
+
+Used by at least 2 projects. Feel free to make a PR to add your project to this list.
