Attempt to sanitize ChatInviteDialog a bit

* Use binds rather than onFoo functions which aren't actually
   handler functions themselves but return them
 * Rename onKeyUp to moveSelectionDown etc,, reserving onKeyUp
   for "a key has been released" rather than, "the up arrow key
   has been pressed"
