PAL version

[NovaSquirrel]

I think it's important to have a PAL version of the game. I think it's mostly a matter of multiplying all speeds by 1.2? And setting music engine flags.

Things that don't work:

• Multiplying speeds by 1.2 (lack of adequate precision means jump heights change a lot)
• Running physics twice every 5th frame (very noticeable)

I think the solution might actually be to add another byte of precision for at least vertical speeds and positions, so that jump heights are hopefully preserved. I would be moving into 12.12 fixed point and most things would ignore the bottom 8 bits of speeds and positions.
