Subject: * Region Terrain textures are now loaded from the RegionInfo class
 rather than being hard coded in the handshake packets. * Supports: Base0-3
 textures, Detail0-3 textures, Start00-11 values, Range00-11 values. * Added
 notes on how terrain texturing works to their definition in regionInfoBase.
