* Added the child_get_tasks OpenSim.ini flag for testing the UDP packet sending code and packet throttler. This flag gets purposely disabled in grid mode. This flag also has the consequence that you can see the prim in neighboring regions without going into them. Be warned, this causes tons of dropped packets.
