Default gcw0 back to adlib emulator due to high CPU cost of fluidsynth.

I'm leaving fluidsynth in the build because the quality is higher and it
does technically work and feel good on several games. Added back in MAD support
for MP3 playback for CD-based music tracks on games like Monkey Island 1 - the
auto-detection seems to not work correctly for gcw0. Default mixer sampling rate
to 48000 due to device driver limitations (this should lower CPU cost since anything
other than 48k gets re-sampled)
