More signal path cleanup, IO now has one deliver_output function that should do the reasonable thing in all cases.

Including deliver MIDI.

You can now create a MIDI Track, run some MIDI through it, and toggle the mute button on and off, hearing either
silence or a large amount of stuck notes depending on your luck.  Woooo.
