Incorporated all changes that were made in SBA V1.5.3 for ZC 1.5.1.

This did include revision of determining previously ordered products that
have attributes and are tracked by SBA.
Wanted to get some of the testing started.  Still have some delete variant(s) based on other actions to do in attributes_controller; however, need to know if have missed anything in the rest of the code.
This should be a break rather than a continue.  Once this criteria is met and $num_rows assigned to 1, there is no reason to continue reviewing to meet the criteria again.

This is updated in the next upload.
