Subject: * Added and implemented the LSL changed event. * An example changed
 event syntax is at: http://opensimulator.org/wiki/Changed_Event_Example * You
 can use this to trigger actions in your script if someone sits on your
 object_rez * You can use this to figure out all of the CHANGED_ constants
 except for CHANGED_REGION, CHANGED_TELEPORT, and CHANGED_ALLOW_DROP
