TurnOver 2.0, build 22.1

Fixed

• One reader speaks at a time whatever the swap setting says. With "TurnOver and VoiceOver swap" off, turning VoiceOver
  on left both talking over each other; now TurnOver goes quiet while VoiceOver is on and running, and comes back when
  VoiceOver goes off (if that is what quietened it). Started with the swap off and VoiceOver on, TurnOver waits and says
  so through VoiceOver.
• TurnOver Settings: Escape closes the window; the app quits with its last window and when TurnOver has gone (left
  running with no window, only a force quit found it); Tab reaches every control in the window, pop-ups and sliders too,
  whatever the Mac's Keyboard navigation setting (with it off, a Tab through Speech met only the ducking pop-up).
  Reported on AppleVis.
• Keyboard navigation (System Settings, Keyboard) is turned on for the Mac once, with a welcome page saying so, since
  TurnOver's Tab needs it where VoiceOver's keys did not.
• Steam and its games always speak through TurnOver where Steam is installed: the switch for it is gone from Settings
  and the Games menu (Steam itself says when it is asked to open its port, so off only hid speech). Reading Big Picture
  and Restart Steam stay.
• NVDA and JAWS keys: Left Option D opens the Desktop folder in Finder, as Windows D reaches the desktop. Asked for on
  AppleVis.
