Import/Export Module System

for osCommerce Online Merchant v2.2

Proof of concept import/export framework. Based on the Easy Populate contribution. Principal changes: 1. Move configuration into database and make more use of existing configuration values. 2. Separate export file layouts from the HTML and each other to allow for drop in installs like payment and shipping modules. Import file layouts are not done yet. However, imports can still be done in the normal Easy Populate fashion. Forum help thread at
