Improvements for mChat like window expansion and disable autoscroll

[Iatots]

Summary (a quick, 2-3 sentence summary): Let people uncheck that "update every 5 second" box, and let people expand the window

Benefits (How this will benefit the server and game as a whole): Makes chatting easier

Details (Description of how you think this would work, the benefits, etc): Why juggle between the current chat and the archive when you can do both at the same time?

Implementation (Optional, if you have an idea how to implement it):

I don't believe our chat supports this at this time. Denied for now.
