(1/2) Volume Rocker:
* Volume rocker music control

Volume Rocker: Switch from Broadcast to Audioservice.
* Fix volume rocker music track seek.
* Minor fixes

Volume Rocker: Do not wake up during track seek.
* After switching to Audioservice track seek works great but it woke the device too if we select both options. Wake only if we do not skip tracks (like raising the volume).
