VID-1780 Move the chat module up when the user is logged in

Its possible and something I contemplated, but its way out of scope for this ticket.  The current rail system has these numbers hard coded everywhere (see https://github.com/Wikia/app/blob/dev/skins/oasis/modules/BodyController.class.php#L129) and coming up with a system for organizing these and updating the code to follow it is significant.  Especially since there's a possibility of the right rail going away.  Good suggestion though!
