   @description: function for outputting embed/object tags for i.e. issue with active x.
   @attibutes: please call with following - divID,codebase,width,height,id,align,movie,quality,bgcolor,wmode in this order as first 8 params.
   anything after this should be "paramName","paramValue" followed in pairs.
   @Function call example 
   <div id="flashContainer"></div>
	<script language="JavaScript" type="text/javascript">
	embedFlash("flashContainer","http://active.macromedia.com/flash2/cabs/swflash.cab#version=4,0,0,0","600","440","main","middle","http://www.virgin.net/cards/ecards.swf","high","#339999","Transperant","salign","T","swLiveConnect","TRUE");
	</script>
	<noscript>This page requires Javascript to be enabled and Macromedia Flash to be installed.</noscript>
	
   @Note: Removed some attributes like quality, seem to be causing type mismatch in ie6.
   
   @have added check flash version so you can use supportedVersion var to decided if to display or not.
   also if you have multiple flash containers on one page please name the flashContainer1, flashContainer2 etc and have the alternative non flash content in
   nonFlash1, nonFlash2 etc.  Make sure they all have a class to hide them initally.  Once the check has been done it will show the relevant divs, ie, either flash content or nonflash.
