SASS Prefix Mixin

/**
	Prefix - Prefixes a property with webkit, moz, or o.

	Usage:

	@include prefix(animation, slide 1s)

	Outputs:
		-webkit-animation: slide 1s;
		-moz-animation: slide 1s;
		-o-animation: slide 1s;
		animation: slide 1s;

	Want to forget Opera or use a different set of prefixes?

	@include prefix(animation, slide 1s, (-webkit-,-ms-))

	Outputs:
		-webkit-animation: slide 1s;
		-ms-animation: slide 1s;
		animation: slide 1s;
