Wikisource category browser now has other languages

I’ve updated the Wikisource validated works’ category browser tool to include other languages. So far it’s just Italian, and to some perhaps-incorrect extent French (there’s only four? that’s not right).

I just need more Wikisources to tell me the names of their validated works and root categories, and it’ll just be a matter of adding these to the config to get them running.

The category list is updated weekly.
