No developer-tools pop-ups on the computers; apps found where they really are; SuperRack and X32-Edit

On a Mac without the Command Line Tools, /usr/bin/python3 is a stub that opens Apple's installer on
that Mac's screen: Woonsocket's Tracks and FOH Macs showed it after joining (and would every ten
minutes). Python now runs on another Mac only when xcode-select says it is there (MIDI reads, MIDI
reconnects, the Computers probe); without it those Macs' own MIDI sessions are simply not read.

The app list used a glob that zsh (the Macs' login shell) turns into an error when one pattern
matches nothing, so no app was ever found there: find instead, and a running program's app path is
taken from the program itself. New recipes: SuperRack SoundGrid and X32-Edit (AUDIO).
Woonsocket now has ABLETON, SUPERRACK and X32 EDIT keys, all OK, and NA's page 99 shows them.
