Subject: AUDIO: Add per sound type mute flag setting to Mixer(Impl).

This also adapts our default implementation MixerImpl to handle the newly
added flags properly.

Now we do not need to set the sound volume for all types to 0, in case we want
to mute them, but instead just set the mute flag for all types to true. This
allows engines to be a bit more agonstic about mute support, when it comes to
volume options etc. since they can just setup any volume they like, but are
still muted (and thus will not break muting anymore).

MIDI sound is of course not affected by this.
