NOTE: This is going to be very much a work in progress so the Operation Stealth's savegame formats that are going to be tried are extremely probably not going to be supported at all after Operation Stealth becomes officially supported. This means that the savegame format will hopefully change to something nicer when official support for Operation Stealth begins.

void Cine::CineEngine::syncSoundSettings ( )

Notify the engine that the sound settings in the config manager may have changed and that it hence should adjust any internal volume etc.

values accordingly. The default implementation sets the volume levels of all mixer sound types according to the config entries of the active domain. When overwriting, call the default implementation first, then adjust the volumes further (if required).

When setting volume levels, respect the "mute" config entry.
The volume for the plain sound type is reset to the maximum volume. If the engine can associate its own value for this type, it needs to overwrite this member and set it accordingly.
find a better name for this
