/*
	Browser detection method
	
	The primary intented purpose is to make it possible to work around HTML rendering issues
	with IE, where the visible positioning of elements would otherwise be off (and it can't
	easily be fixed with CSS).
	
	Sometimes - particularly when addressing cosmetic issues - the only reasonable approach 
	to browser detection is to ask the client what it is - as that's an instance where trying 
	to determine the browser based on available methods simply makes no sense, hence this script.
	
	It checks if it looks like it's really Opera, to save it from the 'feature' of it earnestly
	pretending to be Internet Explorer (because of course it renders dynamic content quite
	differently).
