	Based on Ryber Nyman's script at:
	http://www.robertnyman.com/2006/04/24/get-the-rendered-style-of-an-element/
	
	gets the current style (computed style in Moz/Safari/etc.) of an element
	
	PARAMETERS
	element - object, element node reference
	rule - string, CSS rule
	
	KNOWN BUGS
	- if a property is set in percentages, ems, etc., IE will return the
	  value in the same unit in which the property was set, where Firefox,
	  Safari, et al will return the value in pixels (that's the difference
