* Reverted the Simulator.ParcelOverlay change to an array of enums, Buffer.BlockCopy and Array.Copy both barf. Added a comment that you can typecast afterward to decode the byte

* Finished TerrainManager.DecompressWind() and added TerrainManager.WindSpeeds. Holds a 16x16 array of Vector2s, each one representing the wind speed at a 16x16m area
* Added a WindCommand to TestClient to print the wind speed where the avatar is standing
