FurAffinity (FA) Blacklist wót maleus

Adds content aware blocking for furaffinity.net, which the user can set their own criteria for.

Just click the icon and add any tags, categories, types, or artists that you'd rather not see, and then load FA. Not perfect since some people don't tag their stuff properly, but helps a bunch.

This differs from other extensions in that it uses the real submission information, rather then just searching for keywords in descriptions.
