#4931 SWORD1: Mute setting does not work

[Johannes Schickel]

ScummVM trunk r51098
Linux/amd64 with g++ 4.4.4

The "mute" setting of ScummVM is not respected by the Broken Sword engine at all. This means it can not be used to either mute the sound while the game is running, nor is it respected on game startup.

I tried fixing this by simply adopting SwordEngine::syncSoundSettings, but that messes up the in-game menu screen of Sword1, I guess that is because Sword1 seems to handle the music settings itself via the Music class (same for the SFX/Speech via Sound I guess).

Raising priority. This is a release-critical bug.

Fixed.
