"§e" characters preceeding name

First of all I'd like to thank you very much for this great plugin! It worked absolutely painless, beautiful!

There is just a minor issue I wanted to report: In join/quit messages, the username is preceeded by "§e"

‎matterbridge‎: [api] §eMillesimus left the game

This does not happen for achievements:

‎matterbridge‎: [api] Millesimus has made the advancement [Voluntary Exile]

It happens both with the XMPP and the Mumble gateway.
