Repeat single and mute in Websocket API

[gvolt]

I did not test it, but it could be “repeatSingle” instead of “single”:

socket.emit('setRepeat', {"value":true, "repeatSingle":true});

… command to toggle mute on and off …

Also not verified from my side:

socket.emit('mute');

socket.emit('unmute');
