* Added the ability to restart your individual sims from within them using the estate tools.

* The sims properly restart, however they don't yet notify the existing avatars that they are up.  To see the sim again, you'll need to log-out and back in until I can figure out how to get the proper data to the sims and to the avatar so they reconnect again.
