xm.js
FastTracker 2 .XM player, written for fun.
By default it plays "my dirty old kamel" by Alexander Bulér aka Zalza. I love this tune, and wrote this code just to play it. It can also load some other tunes hosted on my website with a file picker, and it should play just about any .XM file now if checked out and run locally.
It is fairly feature-complete, but is missing a bunch of effects.
