Title: Sound system

I've created the sound system, and added in the engine sounds. This required adding in a keyup listener, and an upUp function. Background music is also included. (At the moment the sound effects were done by a friend of mine, but there are some real ones included in the sound folder. The only thing missing is an asteroid explosion.)
