----------------------------------------------------------------------

Added Karl Kurbjun's sound output patch, cleaned up some output.
Main file is now midiplay.c, midi2wav is still in there for anyone who
wants it. Set sampling rate to 22k, and increased note decay time.
Reduced number of concurrent active voices and made new notes replace
used voices if none are available. This makes lag less apparent.
I really hope this wont go red. (turns around and runs)
