$(window).focus startAuto() when autoPaused

[znebb]

The slider starts always when it was blurred and focused, even when its paused.
The slider should only start, when it was autoPaused.

$(window).focus(function() {
	if(slider.autoPaused) {
		el.startAuto(true);
		slider.autoPaused = null;
	}
}).blur(function() {
	if(slider.interval){
		el.stopAuto(true);
		slider.autoPaused = true;
	}
});
