Added: Random Vanish mode: Arrows go in at the bottom, disappear, get randomized in the middle whist invisible and come out at the top somewhere else :)

Known Bugs: The only major bug i've experienced with this is for some reason the arrows continue past the grey bar even if you get great, perfect or marvellous. This doesn't affect the score though, I can't quite figure this one out.

Added: Hidden and Vanish codes for PIU.
