Added loading and saving of terrain files using Terragen format (Mantis #1564)

Browse Source 
Terrain files can now be loaded and saved using the Terragen (.ter) format.
Selection of the terrain file loader to use is now based on the extension
of the filename being loaded and the data is loaded using a memory stream
instead of writing it to a file and then loading it from the file.
