AbstractSoundManager and implement the actual sound playing with Java sound in
SoundManager and with OpenAL in OpenALSoundManager. I left the SoundManager
name alone so nothing using it will need to change, but if nothing besides
yohoho is using it, I can refactor it to a more sane naming scheme.
Rip out all the music and alternative format stuff since it didn't work anyway.
