- moved subtitle handling to audioplayer,
- neutrino_menue: changed object handling in mediaplayer forwarder
- mediaplayer: usage modes added

user can now open the mediaplayer menu with audio button,
repeatedly pressing as usual the audio button starts up the audio player,
button 'W' starts the internet player.
