		Replaces selected tags with Flash text objects
		Works a bit like sifr - http://en.wikipedia.org/wiki/Scalable_Inman_Flash_Replacement
		but nowhere near as advanced! Before you steal this I would suggest you look at sifr - it's much better!
		If you are hell-bent on stealing this code then please have the decency to let me know that you liked it
		by dropping me a quick email to say - "Hey, I liked it"! Who knows - I may write more and send you the updates!
		If you want the .FLA then let me know.
