Multi-product Add to Cart and Quantity Pricing Group

[Jim]

A patch to fix this issue has been released.

Basically the problem occurred when a product added to the cart by the multi-add-to-cart had a product record number that was less than the number of products added to the cart. In this case the product was record number 3 and there were 4 or more items added to the cart do the code got confused with what products it was working on. (the cart record # 3 or the product database record #3)
