* Implements UserServer logoff in a few situations

* User tries to log-in but is already logged in.  Userserver will send message to simulator user was in to log the user out there.
* From the UserServer, admin types 'logoff-user firstname lastname message'.
* Some regions may not get the message because they're not updated yet.
