message forward to facebook contain no server and username

[GHolk]

I use matterbridge and fbridge bridge facebook and slack,
but in facebook, the messages forwarded from slack are not start with
[slack @username] or my RemoteNickFormat config.

I can send a pull request later.

Did you manage to get it working with the server and username ?

This issue seems to be the same as #4 , I made a PR for this which seems to be a very simple fix : #6
