Set nick and join room

While entering a nick and while present, events seem to get swallowed by
the room. I'll need to rethink my event handling strategy and key
bindings. For the key bindings, I'll either need global bindings that
don't interfere with text boxes, or I'll need modal editing or something
similar where pressing ESC enough brings you back to the global focus.
Global key bindings are things like switching rooms and quitting.
