 *
 * Usage:
 *
 *	myFlash = new FlashObject("path/to/swf.swf", "swfid", "width", "height", flashversion, "backgroundcolor");
 *	myFlash.altTxt = "Upgrade your Flash Player!";                // optional
 *	myFlash.addParam("wmode", "transparent");                     // optional
 *	myFlash.addVariable("varname1", "varvalue");                  // optional
 *	myFlash.addVariable("varname2", getQueryParamValue("myvar")); // optional
 *	myFlash.write();
