Add the source wav files that I used for the sound samples and add a script which I used to convert them to a raw format that can be played on the GS. That should make it easier to modify the sounds if necessary in the future. Converting the sounds from wav to raw is not part of the build. The raw files themselves are committed in the repository although the build could be changed to generate the raw sounds at build time.
