Apollo Beach on its own: a standalone panel to send them

- tools/standalone.py builds dist/<Name> Status Panel.zip: program, install.command, READ ME FIRST.txt
- setup --standalone: campuses.json standalone, tells nobody, no hub, no NA key
- Standalone backs itself up nightly to ~/Documents/Status Panel Backups/<id>
- upgrade-companion --from <.dmg/.zip from bitfocus.io> (no NA needed)
- Only the hub lists campuses or shows other campuses' install lines
