Changeset 7855 for code/trunk/src/orxonox/sound

Message:

fixed a bug which caused the application to crash if the game was ended while cross-fading ambient sound. in particular AmbientSound registered itself again at SoundManager as soon as SoundManager was deleted. added a bool to prevent this behavior.
