Chat functionality almost complete.

I have written public methods for leaving a room and for sending a room message today. The receiving of room messages also works now, and the LoneSeekGUI project (my test application) shows how to use it! The only things which are missing missing by now, are:

• Room tickers (not really important though)
• Private messages (they are important)
• And the notifications when someone leaves/joines a room where you are in (important too, since I have to keep the user list in sync).

Good new stuff, isn't it? :). I also made some improvements on LoneChat (the IRC alike SoulSeek chat client), though it is not yet usable.
