Apple-W to close a chat tab/window.

This should work as of r7111

As mentioned on http://www.igniterealtime.org/forum/thread.jspa?messageID=138999&tstart=0#138999, as of 2.4.1 ctrl-w doesn't close chats either.

I do appreciate the work done on this issue, but it is not quite right yet
Apple-w still does not close a chat window, Ctrl-w does, and looking at the diff that seems to be what was coded in...

Incidentally, Apple-w (or Ctrl-w) does not close the main spark UI either which is something else that would need to be fixed to satisfy mac users.

This definitely still occurs in 2.0.7

This issue still exists as of Spark 2.0.7.
