Minimum Price Qualifier with Fixed Amount Off per Qualifying Item Results in Wrong Discount Amount

When using the Minimum Price Qualifier with Fixed Amount Off per Qualifying Item, uc_discounts_alt uses the sum of prices times the amount that is supposed to be discounted for each item, rather than *quantity* of qualifying items. So, if you are trying to have a discount that gives $2 off each product over $10, and you have a $10 product in the cart, the discount will be $2 * $10 ($20) rather than $2 * the number of qualifying products.

The incorrect calculation is performed in the code block below, but solving this problem may require a more involved solution than changing the line the calculates $discount->amount, since we either need to change $order_qualifying_amount to provide a quantity amount, provide a new variable, or go straight for the ideal solution, which would be to completely refactor discount application and qualification processing.

      case DISCOUNT_TYPE_FIXED_AMOUNT_OFF_PER_QUALIFYING_ITEM:
        //Discount is the total quantity of qualifying items in order (order_qualifying_amount)
        //times the discount amount
        $discount->amount = $discount->discount_amount * $order_qualifying_amount;
