Simple Price break

for osCommerce Online Merchant v2.2

this contribution allow prices break for products. It adds a new field in the admin/product description in what you enter the discounted price per quantity in the same way you can enter the price range in the spedition module. For example : 10? for 1 to 9 parts 8? for 10 to 99 parts 5? up to 100 parts You enter 10 for the product price. 10:8, 100:5 in the new field. This code automaticly add a tab at the end of the product description to show the price break to the customer. I wrote this code because my own code is too modified to add the price break contribution. This one is "easy" to install and don't modify lot of code.
