Fixed SFML Audio System
Cheeseboy had SFML set as the default for all platforms and Josh merges
it without having anybody test it, way to go both of you fucking morons.
I also added the copyright headers and changed the file names to work
with eurl.
Added LateralGM Buffers
Made the audio system function for adding a sound from buffer from LGM
work and now cheeseboys audio system is good to go.
