Fixed SPEEDMUSIC is still broken

[Liliam]

The level header variable SPEEDMUSIC doesn't work as it's supposed to. It speeds up the music when Speed Shoes are picked up, but it never slows it back down to normal.

This is funny.

It's broken due to my attempts to not reset the speed of the music every time something that normally resets the music happens. Mainly because I was asked by someone who I think loved to hear The Final Countdown at 2x speed all the time or something. =P ​
