Upgraded libcommuni to 2.0.1
Added two new data roles for a user standard item: sort and name without prefix.  Now we sort by user role, and search by the un-prefixed name.
Instead of having the gifs tell the window to redraw, (which after several gifs at different frame rates, happens all the time),  redraw every 100ms, which is typical redraw for web browsers. (10fps)
Created the UI for the preferences window
Deal with notices from nickserv and chanserv
Don't lowercase channels and users when we add them.  I think this was causing more trouble than it was worth, and the servers are consistent at sending names with a consistent case.  Also use delete later instead of delete, because it's 'smarter'.
Fix user sorting
