addresses: Rotation of terrains varies between all the formats,
Raw and R32 seem to be the same, while PNG, JPG, BMP all seem
to be rotated 180 degrees different.
* 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.
