I've made the french translation of the language file. This is my native language and I checked with an integrated kitchen vendor to make sure I was using the right terms and not what little idiom remain, so it should be accurate.

fr_fr.zip

It's better to make a pull request (and easier for the developer).

Oh, I see, thank you. This is my first actual contribution aside from raising issues, so now I've looked up the documentation to do this properly.
It'is now in pull request 411.

Thanks.
