Reworked the categories of industries. We've got more of them, better named and they cover all the different products and services advertised. Most notably Food, Alcoholic Drinks and Non-alcoholic drinks are separated from each other.

The next task will be to find a nice way to link campaigns together. Also, flickr style taging was suggested by readers. Let me know if you have any other suggestions.
