Minamp 1.9: install internally, resume after Bluetooth dropouts, log why playback stops

Installed on the SD card (installLocation auto), Minamp was killed whenever USB
storage was turned on. A2DP dropouts send AUDIO_BECOMING_NOISY like an unplug:
after a Bluetooth loss, resume if the speaker is back within 20 s. Focus loss,
media buttons and stream failures now go to the connection log.
