Exclude Products from Promotions

Creating promotions that apply to a category, product group or the entire catalog is not possible of certain products are set as "Not Equals" in the rule manager.

We should be able to exclude products from promotion so that the user can still receive the promotion and purchase the non-promoted product in a single transaction.

Current Functionality Example: The site has a 25% promotion that is global, however, Product A, B and C are not included in this promo. A user adds a few different products and then navigates to the cart page, their total is reduced by 25%. The user then adds Product A to the cart and the cart total is 100% for all items, the 25% is removed completely.

Expected Functionality Example: The site has a 25% promotion that is global, however, Product A, B and C are not included in this promo. A user adds a few different products and then navigates to the cart page, their total is reduced by 25%. The user then adds Product A to the cart and the cart total for only the eligible products are reduced by 25% while the portion of the cart total for Product A is not.
