Recover from playback stalls; cap quality over Bluetooth

On the Galaxy Mini, Wi-Fi and Bluetooth audio share one radio: streams starve
and the media player then sits at the same position forever while showing
playing. After 10 s without progress, recover like a network failure (reconnect
and resume, then download first, then skip). New setting: quality over
Bluetooth (default 192 kbps) to leave the radio airtime for the speaker.
