varregion: serious rework of TerrainChannel:

Browse Source 
-- addition of varaible region size in X and Y
    -- internal storage of heightmap changed from double[] to short[]
    -- helper routines for handling internal structure while keeping existing API
    -- to and from XML that adds region size information (for downward compatibility,
        output in the legacy XML format if X and Y are 256)
Updated and commented Constants.RegionSize but didn't change the name for compatibility.
