Buddy Names in Chat doesn't work

probably related to #196 (buddy icons)

Maybe slightly. I noticed that after a restart, Colloquy indeed shows the buddy names in the member list. So it is also a refresh issue. But next to that, the buddy names are not used in the transcript pane so you still see the original irc nicks there.

Another thing: I was wondering... nick-completion in the input pane (pressing tab key)... how would this work with buddy names? I'd say that Colloquy should be so smart that you can either use the nick or the buddy name there. So if a persons nick is 'bilbo' and his buddy name is 'Peter', I'd add both names to the completion-namespace. Another issue for the transcript window. If it shows the buddy names there, it would be handy for some situations to know the nickname. So a hover over the buddy name could show his current irc-name in a tooltip.

Just some thoughts :)

Would be really cool if this will work (again).

Cheers.
