Only categories which contain items will now appear in the category selector when browsing seller stores.

It is now easier for buyers to browse seller's stores because they do not have to look through all possible categories. Buyers are only presented with the categories for which a store owner has items listed.

Store owners do not typically have items in all possible Webstore categories (Webstore now has over 4,000 unique categories thanks to member suggestions).

Another great idea suggested by a Webstore member!
