In the last commit I added the support of an existing chiptune: klystron.

It is clearly an awesome news and it will allow us to do much more things. Right now you can always use classical WAV files for your musics/effects, and in the same time use the chiptune to do more 8bits stuff :)

It will be possible to create on the fly the musics/effects via the API or the editor, and to load others formats (XM for example).
