* This update contains a bucket-full of network optimizations.

* ParcelProperties are sent only when needed instead of on any movement
* Terse Updates and other temporary data packets are marked unreliable
* After a certain amount of users, the sim actually sends updates on things less
* Experimental
* Tested to 68 avatar with pCampBot  (And it's surprising what actually causes the most lag..  the text chat!)
