Adding a translator for french union catalog CCFr

As requested in [Zotero Forum](https://forums.zotero.org/discussion/37503) I've built this first version of a translator. 

It still misses somes specific cases but works for > 90% of records I'd say. CCFr catalog is full of JS, not that easy to parse.

Tests are style missing, hope it's not blocking.
`url.indexOf(".....") != -1`, but just add this to the target regexp and you won't need this filter (it's also more efficient that way). Make it `^http://ccfr\\.bnf\\.fr/portailccfr/.*\b(?:action=search|menu=menu_view_garappage)\b`
