ZC 1.5.1 update of zen_Bundle to permit continued operation

1. Updated the order.php file to recognize the use of the orderWatcher class.
2. Corrected the shopping cart where each product that did not have an attribute
	would throw an error.
3. When a product with attributes was displayed as a part of bundle the
	attributes were presented in a "random" (consistent) order and
	regardless of the setting of default in the attributes manager
	the first attribute in the list would be the "default".  Corrected
	the sorting of the values and assigned the default. The sequence
	of option names was not directly affected; however, may be
	sequenced correctly inadvertently.
4. This plugin introduces a new product type of product_bundle; however,
	there are standard actions to be taken when creating a new product
	type as identified on the Zen Cart website.  One of these things
	is to change the notifiers in the event that they are used in the
	future.
5. Also there are some aspects of ZC 1.5.1 that were introduced to address
	preventing indexing pages.
