Subject: [PATCH] Removed tabs in chat lobbies: - unsubscribed lobbies display
 complete info in a blank page, with some additional help - double click to
 subscribe. - added unsubscribe button to ChatLobbyDialog. Needs a more
 appropriate icon (e.g. An open door with a leaving arrow) - the lobby list is
 now used to display typing status. It could be used to show all sorts of
 info, the exact same way, such as joining/leaving peers, etc, using various
 different icons.
