Translation done. There might be some minor changes to be done after I've submitted my work to the French speaking community.

However I've tried my modified version of the addon but it still shows in-game in English (although the "corerofiles" tab is in French and has always been). I can't figure out a way to see my changes ingame, still trying. I guess there's something to change in a config file to tell the addon which language to use ?

I've hosted my preliminary work here : http://www.chez-cheos.org/jamba/Jamba-0.5d-fr.zip (please be gentle to not download it if you don't need it because I have limited bandwidth )
