* discord: add nosendjoinpart support
This allows the discord bridge to be configured with `nosendjoinpart`,
preventing discord-originating join/part messages from being send to
other bridged platforms.
* discord: Ignore incoming events for other guilds
Ignore all incoming discord events originating from Guild IDs other than
the one we have configured.
This is necessary because discord bots receive events for *all* discord
guilds that they are present in.
Fixes#1612
Matrix quotes replies and as of matterbridge 1.24.0 we strip those as this causes
issues with bridges support threading and have PreserveThreading enabled.
Introduced via 9a8ce9b17e
But if you for example use mattermost or discord with webhooks you'll need to enable
this if you want something that looks like a reply from matrix.
See issues:
- https://github.com/42wim/matterbridge/issues/1819
- https://github.com/42wim/matterbridge/issues/1780
Sorta regression introduced by 9a8ce9b17e
which changes the way we get replies of matrix.
This causes issues like https://github.com/42wim/matterbridge/issues/1780
We "fix" this by mimicking the old behaviour when "PreserveThreading" is
disabled.
We create a new event EventFileDelete which will be used to delete
specific uploaded files using the Extra["file"] in the config.Message.
We also add a new NativeID key to the FileInfo struct which will contain
the native file ID of the sending bridge.
When a new file is added to the config.Message.Extra["file"] map, now
the bridge native file ID should be added here.
When the receiving bridge receives such a message, it should keep an
internal mapping of NativeID <> bridge fileid/message id. In the case of
discord we map it to the resulted discord message ID after uploading it.
Now when a bridge deletes a file, it should send a EventFileDelete and
setting the ID to the native file ID of the bridge.
When the receiving bridge will get this event it'll look into the
NativeID <> bridge id mapping to find their internal ID and use it to
delete the specific file on their side.
For now this is implemented for slack to discord but this will be add to
other bridges where useful.

* Fix typo
Without this declared, it seems that Discord will not send any member update
events after connection, even if the privileged gateway intent is enabled for
the bot in settings. This causes nick tracking to get out of sync when people
change their nicks after the bot connects.
See: https://discord.com/developers/docs/topics/gateway#gateway-intents
Webhooks don't support the threading yet, so this is token only.
In discord you can reply on each message of a thread, but this is not possible in mattermost (so some changes added there to make sure we always answer on the rootID of the thread).
Also needs some more testing with slack.
update : It now also uses the token when replying to a thread (even if webhooks are enabled), until webhooks have support for threads.
When using the webhook, the previous method to edit a message was to
delete the old one via the classical API, and to create a new message
via the webhook. While this works, this means that editing "old" messages
lead to a mess where the chronological order is no longer respected.
This uses an hidden API explained in https://support.discord.com/hc/en-us/community/posts/360034557771
to achieve a proper edition using the webhook API.
The obvious downside of this approach is that since it is an
undocumented API for now, so there is no stability guarantee :/
When a webhook "edits" a message, it does this by deleting the message
and creating a new one with the new content.
On creation of this new message, we'll get another ID then already is
know by the gateway in its id cache. So we add it in our own cache and
replace it whenever we want to edit/delete it again.
This adds support for the discord category option that can be used
to group channels in. This means we can have multiple channels with
the same name.
We add the option to specify a category in the channel option of a
discord account under [[gateway]]
Besides channel="channel" or channel="ID:channelID", now also
channel="category/channel" can be specified.
This change remains backwards compatible with people that haven't
specified the category and incorporates the fix in #861
* Support webhook message deletions (discord)
Messages sent via webhook can now be deleted. It seems it can do this
without any special permissions.
This copies discordgo.WebhookExecute and makes it support the returning
of discordgo.Message.
A pull request has been sent upstream, so we should use that if
@bwmariin accepts the pull request:
https://github.com/bwmarrin/discordgo/pull/663
Changes in behaviour (webhook mode only):
- Previously messages *edited* on other platforms would just be
retransmitted as a brand new message to Discord.
- Message *edits* will now be ignored.
- Debug: message edits will now print out a "permission error".
In the future it may be good to send an "message edited" react to those
webhook messages, so at least people know that the message was edited on
other platforms. (Even though it can't actually show the new message.)
Alternatively, message edits could just send a brand new message with a
link back to the old one. This is a little ugly but it would ensure that
Discord users are able to see the edited message. These "message edit
notifications" would be sent from the bot user (not from a webhook), so
we could edit the "edit notification" if subsequent edits to the
original message are made.
