* This is a HUGE OMG update and will definitely have unknown side effects.. so this is really only for the strong hearted at this point. Regular people should let the dust settle.
* This has been tested to work with most basic functions. However.. make sure you back up 'everything' before using this. It's that big!
* Essentially we're back at square 1 in the testing phase.. so lets identify things that broke.
Change user server to handle attachment assets record properly. Ensure
that attachments are not re-rezzed on region crossing. Persistence
will NOT WORK with earliser UGAI!!
Change region server to match.
* 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.
* Added new generic "Location" class to handle 2D integer locations. Going to use it to replace all RegionHandle and X,Y coordinate references throughout the entire project. You have been warned.
* Added a Logout message with a name on the console
* Added a *fixme* message to figure out why the current agent session is null
* After updating you may notice that there's a login <user> and also a logout<user>
