export for kelkoo in french

for osCommerce Online Merchant v2.2

Instructions and comments in french only sorry for non french-speaking people. If needed I will translate it, or maybe some french-speaker out there will. This module creates an export file in text format for kelkoo. There is also an admin part to choose products that will appear on this export, and define with a few caracters a shipping price. This contrib needs just a few modification to be able to export in xml format. Vinioute
