This does everything the existing code does, but trying to integrate right now

is kind of difficult.  The plan is to use this in a new PidginInfoPane I have

started, but that change got very large so I just packed it into the end of

the existing info pane.
The only things that are not implement right now, are making menu items

insensitive and that's because we need to figure out a better want to handle

custom avatars for users.

Ran locally.
