GOB: Add support for saving true color sprites

Not exactly the "nice", since up-depthing the sprite data to 24bit
happens after it has been adapted to the current system's color
format, so we're going to gradually lose precision when the save
gets passed around different systems. Still, this is the least
headachy solution, I guess...
