/**
* A more advanced version of our writeFlash code that uses SWFObject to perform Flash Player version detection and to write out the SWF Object itself.
* If user does not have Flash installed, or too low a version of Flash, a message informing them of this (including a link to the Flash Player Download
* page) will be written to the DIV instead of the Flash content.
* @author Matthew Leathes (SWFObject by Geoff Stearns)
* @version 2.1
* @history 26/03/2007 ML: added version 1.5 of SWFObject (version 2.0 wasn't a 'real' release)
*	@history 06/12/2006 ML: Added version 2.0?? of SWFObject, put these header comments in for compatibility with FlashCreate commenting system, changed 
* URL of FlashPlayer download link to point to adobe.com instead of macromedia.com and saved that link in a var instead of hard-coding it.
