Podlite 1.12: set speed and skipping silences before the audio opens; reopen on a skip toggle

ExoPlayer 2.18 sets up skipping silences when it opens the audio, so the engine now gets both settings before
prepare, and turning the option on or off while an episode plays reopens it at the same spot. Tested on the
Xperia J against test/mock_abs.py: 2x speed, silences skipped, the toggle mid-play, notification buttons.
