Subject: Plumb in the presence notifications and region shutdown/restart
 messages from the presence module to the message server, through the user
 server and on into the database. This should fix the "Already logged in"
 issue that grids see after a sim crashes, or a user crashes out of a sim. Not
 yet a 100% solution for friends, but getting there.
