Backport from the iOS version: never mark early endings as played, stall warning, Close

- An episode only counts as played when playback reaches the last minute.
  Saved files that "complete" early (cut-short download, SD card problems) were
  marked as played on the server, as were streams ending 30-60 s early; now a
  stream is retried and a file is reported.
- "Playing" but the position not moving for 12 s: say so.
- Menu -> "Pechar MiniABS" (Latest/Shows/Saved and the player): save the
  position, stop playback and close the app.
