* You'll need to start-up the MessageingServer and set it up. It sets up like any of the other grid servers.
* All user presence data is kept in memory for speed, while the agent is online. That means if you shutdown the messaging server or the messaging server crashes, it forgets who's online/offline.
* Occasionally the region-cache will get stale if regions move around a lot. if it gets stale, run clear-cache on the messaging server console to clear the region cache.
* Added new generic "Location" class to handle 2D integer locations. Going to use it to replace all RegionHandle and X,Y coordinate references throughout the entire project. You have been warned.
* Cleaned up copyright notices in AssemblyInfo.cs's
* Added Copyright headers to a bunch of files missing them
* Replaced several common string instances with a static constant to prevent reallocation of the same strings thousands of times. "" -> String.Empty is the first such candidate.
