Unlocking more levels

To unlock (all) of the levels, fill the range 0x08 to 0x28 with "FF". So far this has caused no problems, and allows you to add more levels to the game. Levels will not be visible unless there is a corrisponding LevelX_Final.dat in the Gamedata folder, and an ONLD that matches the level number in the level0_final.dat.
