Start of work on translations: "Work in Progress" message and index-fr

Changes:
Made the Work in Progress bilingual
Created the french Index page, fully translated.

While I am French, I offer no guaranties on the quality of the translation. It is all I can do today - hopefully I can do more in October.
« gestionnaires de l'information ou de l'architecture » devrait être « gestionnaires et les architectes ».
