 * Programmer: Robert Giddings                Date: 12/01/2011       *
 *                                            Version: 2             *
 * Standards : v1.15                          Project: SDR00552      *
 * Reason: 	Added document.addToBasketForm.qty.value=1; to reset 	 *
 *			value that might be in the session due to manual buy now *
 *			qty box. The buy now buttons that use this method don't  *
 *			have a qty box next to them, but they use the same 		 *
 *			action.											         *

 * Standards : v1.15                          Project: SDR00552      *
 * Reason: 	Made addToBasket() ajax based.						   	 *
