#1 Revamping how sounds are loaded and played

[Cyde Weys]

At the moment, audio files are stored in the form of mp3 and wav and loaded using three external jar libraries. I wasn't the one who coded up this section of the code, and so I don't really know how it works, but my guess is that it could be a bit cleaner. Also, copyright status of these libraries is unknown. I suspect, but cannot prove, that they are free.

If we can find anyone who's done sound for games, that'd be good. It might make sense to convert the mp3s to oggs and use a better decoding library or something.
