* Added some inter-region comms glue for allowing sims to chat amongst themsevles about an agent behind the agent's back.

* Will be using this glue Tomorrow/today to tell other regions what the agent's draw distance is and what region they're actually in so the region can make decisions on what prim to send, if any.
