Audio mode for each playlist entry (#909)

- Playlist entries get a second select slide for the audio mode (normal, instrumental, vocals, karaoke)
- The slide is only shown if the song has an instrumental file, otherwise normal is used
- The audio mode is saved in the playlist file and used for each round
- Sing, score and highscore screens use the audio mode of the current round
- Song options select the audio mode by mode instead of position
- ScreenSong theme version 15
