Subject: * Cleaned up code in Terrain, Tree and Map modules. * Fixed a bug
 with Terragen loader where it would do bad things on a non 256x256 sized
 terrain. Now loads the array correctly. * Moved MapImageModule.cs to
 Modules/World/WorldMap * Changed Location.RegionHandle to use
 Helpers.GetUlong instead of doing it ourselves.
