French

* Some sentences may require some changes, especially in the "conditions" file (I left the original english sentences in comments so any other contributor may provide a better translation easily)
* I left words like "changelog", "login", etc. in english
* in the first commented lines in each file I set "language: Français" ... maye be changed to "language: French" if required
* Hope I didn't left syntax errors left (like missing commas) ...
