Small patch for Classic!

I finally (for real this time) fixed the warp zone audio bug! I rewrote a lot of the audio code, so everything works. I did more cleanup to improve on the efforts I made last year to fix up the code base, but it still sucks lmao. I also updated some of the art to the new game's textures. I might have a few more coming out we'll see. I did this because it was bothering me, and I had a little bit of time to spare.
