Live-adjust of master volume levels

[Bejoscha]

Could the player offer two "master" sliders for volume so that one can fade/mute the two levels (foreground/background) actively without changing the adventure-scene and without stopping the track. (One might want to reduce a background track for a while without actually stopping it.)

Some form of master volume control is certainly desirable. I've run into this issue myself several times.
