f - change music

Notes:

This is a straightforward tetris clone with good playability at faster speed levels in mind. For example, the key cooldown gets smaller when you advance levels. It has got 3 music tracks (and a secret one) so you don't get too bored too easily. Fleshing out appealing aesthetics was quite tricky and this thing took me overall about a week. The score calculation and game speed is quite equal to the original Tetris, I changed the response time of the controls a bit to my liking, but somebody who knows the original should feel immediately at home :-)
