DABplay+ 1.3.2

Fixed

• On some head units the system bars still came back after leaving the app and returning, until Full screen was
  switched off and on again (#2). Older Android versions (8 to 10)
  ignored the request to hide them again; DABplay+ now makes sure it takes.
• Some C100 sticks often didn't work when the app started (#3):
  their DAB chip needs a moment after power-on, and DABplay+ asked only once. It now waits for it, the way other DAB
  apps do. A failed switch to another channel no longer resets the whole dongle either.

Changed

• While a connected dongle doesn't respond, the app says "DAB dongle not responding, retrying…" instead of "not
  connected".
