Embargo v.1.0.0

for osCommerce Online Merchant v2.2

This contribution for ocCommerce checks if a specific country may not be delivered. Setting which country has an embargo is done in the admin area. Story: As I lunched a store at http://www.bavaria-schnaps.biz to sell traditional bavarian schnaps, I ran into the problem, that some countries are prohibiting sending alcohole via postal services (e.g. the United States). Therefor I wrote this contribution. Customers can register from every country in the world, but the delivery is only allowed in certain countries. If a user tries to give a delivery adress in a prohibited country, a message occures and he is asked for an alternative adress. The right german wording would be "Liefersperre" or "Ausfuhrsperre", but I called it "embargo". Language files are only in german, but there is not much text. Should be easy to translate it. This is my first contribution, so dont blame me to much ... ;) Tested with OSC-2.2MS2
