varregion: plug in TerrainData class and modify TerrainModule and LLClientView to use same. This passes a terrain info class around rather than passing a one dimensional array thus allowing variable regions. Update the database storage for variable region sizes. This should be downward compatible (same format for 256x256 regions).
