CRE Loaded 6.15 - contribution: fast easy checkout

Hi We run CRELoaded 6.15 with a few contributions. 1. We need to convert the OSC-Contrib: Fast Easy Checkout to CRE 2. In Switzerland we have a so called vRG, a recycling-fee to be paid for every product buyed. We would like to enter this product-dependent fee directly below the weight field. this fee should not be shown on product info but in "shipping cost estimator" in the cart and then in the summary before confirming order....see attached files. I will do the translation in german and french if you just speak english. I will send you all files and a db-dump from us for developping.
