Subject: iOS: Audio remote control, Now Playing info

Update the basic Now Playing info about the currently playing music, and respond to remote control commands.

Seems to work with MP3 but not other audio formats, probably because those are played via custom decoders. There must be some API for updating the playback status manually.
