* Sanity check in DeserializeLLSDXml() to return an empty LLSD block instead of throwing an exception

* Removing redundant code from OpenMetaverse.Utilities
* Using System.Diagnostics.StopWatch instead of Environment.TickCount for rate limiting, and speeding up packet sending from 75ms gaps to 10ms (might be slightly too fast, but it works for me)
* Cleaning up the logic a big in RequestAllSimParcels()
* Try/catch block in GridProxy around packet delegates
