Subject: * Disabled ancient TerrainEngine. * Enabled new TerrainModule.  (The
 king is dead, long live the king!) * Use the console command: "script terrain
 save file.r32" / "script terrain load file.r32" to load/save terrain. Now
 uses the extension to determine file format. * MANY of the old terrain
 features do not have a replacement function in the new module yet, this needs
 to be corrected, but has not been done so far. This being said, the new
 module is faster and more efficient and should be a good replacement.
