v0.22.6.4

Somewhat improved since the last time... MIDIBEEP.EXE sounds more natural (though still incredibly wonky), and has a quit key (so long as the track isn't just one long pause).

v0.22.6.2 PREVIEW

NOT ready for prime time. Just a preview of the first rough implementation of the DOS-based MIDI beeper for those who don't want to go through the hassle of compiling it.
