* Start passing around a region server's http port in RegionInfo.

* This means that caps methods (editing scripts, poss map functions, etc) on non-home regions should now work with servers which are listening for http ports on a non default 
(9000) port.  
* If you are running a region server, this may only work properly once your grid server upgrades to this revision
* PLEASE NOTE: This shouldn't cause inter-region problems if one end of the connection hasn't upgraded to this revision.  However if it does, the instability will persist until 
the grid and region (and possibly all the region's neighbours) have upgraded to this revision.
* This revision also adds extra login related messages, both for success and failure conditions
