Implemented remote play controls in the PlaylistService - if a host connects, it
uses a RemoteAudioPlayer player, which sends messages to the host to play, pause
and skip music
Implemented isPlaying for remoteaudioplayer...this is still not 100% as we need
messages from the host to the fan for it to be completely correct

Added code to make sure icon switches properly even when remote played
Small changes to remove commented code or add comments
renamed musicAdapter to mMusicAdapter
