/*LIGHTBOX
	a lightbox is a box of content that sits above the main area, which is usually faded out
	designed as an object because validation needs to access some of its functions.
	setting up the tint bg element at init phase works around a obscure IE bug
	REQUIRED:
		class 'PE_lightBox'  (NB case-sensitive) on the div to become a lightbox, this area must also have an id
		class 'PE_lightboxOpen(id_of_lightbox)' on the anchor that triggers the lightbox if triggered by a link
		class 'PE_lightboxIfInvalid(id_of_lightbox)' on the div with the PE_validate() class if the lightbox is triggered by an invalid field (see validate section comments for further details)
	UPDATE : 12.10.08 
		lightbox will now read if it is to load in a flash video player by reading the format of the href of the link that fires it.
		When this happens it takes the Heading text from the link title and the format from an additional class:
			'F_(large)' or 'F(small)'
		It will also use this information to size the content div to the dimensions selected and the flash will be loaded after the lightbox appears.
