player: Pause and mute out when the app goes to the background

Browse source 
Pressing HOME kept the audio running, so a video started in another
app played on top of it and returning landed on the home view with an
invisible player. The player now pauses itself on ON_PAUSE, reports
the position to the server and resumes automatically when the app
comes back. The playing screen is also kept across activity
recreation now, so returning shows the video, not the home view.

Ref #6
