Added delay option

Allows you to tune your animation timings or create simple cascading animations. A typical example of how you could use this is below.

	$('h1,h2,h3,li,p', '#home').css('opacity', 0).each(function(i) {
		$(this).animo({ animation: "fadeInLeft", duration: 0.3, delay: i*0.1 });
	});
