Make random option display all slides before repeating

Hacked this into getNextViewId() of slideshow.min.js in case anyone else needs it:
Also requires adding var randomShuffle =[]; to the top of slideshow.min.js and the shuffle function below:

function getNextViewId(){
	if($settings['random']){
		if (randomShuffle.length === 0) {
			for (index = 0; index < $views.length; ++index) {
				randomShuffle.push(index);
			}
			shuffle(randomShuffle);
			return randomShuffle[0];
		}
		var viewId=$currentViewId;
		var shuffler = randomShuffle.indexOf(viewId);
		shuffler++;
		if(shuffler > randomShuffle.length-1){
			return randomShuffle[0];
		} else {
			return randomShuffle[shuffler];
		}
	}
	var viewId=$currentViewId;

	if(viewId==undefined)return 0;

	if(viewId>=$views.length-1){
		if($settings['loop'])
		return viewId=0;
		else return $currentViewId
	}
	return viewId+=1
}

function shuffle(array) {
   var tmp, current, top = array.length;

   if(top) while(--top) {
   	current = Math.floor(Math.random() * (top + 1));
   	tmp = array[current];
   	array[current] = array[top];
   	array[top] = tmp;
   }

   return array;
}
