* Opportunistically preserve Slack threading when parent thread in cache. [#529]
* Removed slack-specific processing from gateway.
* Added docs.
* Add option to enable threading, with default to off.
* Did cleanup on @42wim's comments.
* Update gateway/gateway.go

* Suggestion from @42wim :)
* Suggestions from @42wim.
* More suggestions.
In order to support extra use cases we should add the `{GATEWAY}` tag to the `RemoteNickFormat` string which would be replaced by the value of the `name=` field from a gateway's configuration.
This is _very_ useful when you are forwarding, for example, multiple channels from one chat to a single channel on another one (one-way). It will help you identify the source channel of a message on the target chat.
* Add config option MediaUploadPath
MediaDownloadPath can be used instead of MediaServerUpload, for when your
webserver is on the same system as matterbridge and matterbridge has
write access to the serve dir.
* Limit length of hash in MediaServer urls to 8chars
Full SHA256 is unnecessary for uniqueness.
Also; if a file has the same first 8 charachters of the SHA256 hash,
it's still not a problem, as long as the filename is not the same.
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.
