Extends jQuery.animate() to automatically use CSS3 transformations where applicable.
Tested with jQuery 1.3.2+

Supports -moz-transition, -webkit-transition, -o-transition, transition

Targetted properties (for now):
	- left
	- top
	- opacity
	- width
	- height

Usage (exactly the same as it would be normally):

	jQuery(element).animate({left: 200},  500, function() {
		// callback
	});

	0.4 (05/10/2010):
		- Iterate over multiple elements and store transforms in jQuery.data per element
		- Include support for relative values (+= / -=)
		- Better unit sanitization
		- Performance tweaks
