deleted a bunch of extraneous stuff in shaders
i am liking it so far. now you play a cymbal sound when you move.
Audio is now synchronous.
- However, trigger track does run a little fast over time (bug).
- I'll switch it to .wav to see if it syncs better.
- Even if this approach works, audio needs to be periodically re-synced.
GLstrings are initialized better.
- Probably want to move entirely to spritesheets though.. who wants to
  see a player made of text?
