Support to repeat one song in Audio Player.
Repeat mode can be 3 states.
A) Stop playing when all songs have been played.
B) Keep on playing by same order when all songs have been played.
C) Set a single song to repeat.
Created a repeat-button that has 1 state (A) as the OFF, and 2 states (B/C) as the ON in toggle-button in order to show all 3 states visually.
