Added in new BGM, took out old BGM, added in new SFX.  Moved the Music Game Object to the Sound Manager since it makes more sense over there.  Added fading down and up as 2 seperate functions for Crossfade.cs.  Added in a new AudioSource for SoundManager.cs that is the new SFX.  Added in a call to the SFX in MoveState.cs so that you can hear walking noises as you move about.  Added in a cheat for testing.
