Updated po files and fr po file

Sorry for that, but as my skill in git or github is not so high, I don't know how to split in 2 different pull request the changes I made to my repository. So I send you a unique pull request containing 2 commits from my repository:
- first one - updating all po files according to the new pot file
- second one - updating fr po file with new terms translated

Hope this will be useful for you. Tell me if I can do something to make this more easy for you to merge.

Cordially,
