Subject: Added kUnsupportedColorMode error code brought Scumm engine and SDL
 backend into compliance with API outlined in
 http://scummvmupthorn09.wordpress.com/2009/06/14/how-this-is-going-to-work/
 Provided convenient Graphics::PixelFormat constructors for ColorMode enums,
 and bitformat integers. Removed last vestiges (I think) of initial cursor
 hack.
