configure: implement --with-audio=(no|yes)
This adds the ability to turn off the audio/music parts of the
API, removing the SDL2_Mixer dependency when disabled.
It will also automatically disable the audio/music parts of the
API when SDL2_Mixer isn't detected @ configure time and
--with-audio was unspecified.
It's a bit ugly with a bunch of #ifdef's in play.c, oh well.
