- cleanup of sound system startup and menu handling:
* added global functions that check whether FMod and OpenAL are present, without initializing the sound backend. * make sound init code more fault tolerant. It will now try to switch between FMod and OpenAL if the currently active one cannot be found but the other one can. * added 'ifoption' checks for sound backend to menu code. * only show sound backends which are present and hide the options for the ones which are not.
