french translation correction

Hello,
here is a small request to correct the translation of the word "order". It was translated with the _commercial_ meaning («commande», as in Cartridge) where we expect the _numerical_ meaning («ordre»).
Meanwhile, I will make a pull request for Cartridge, since we need to had some context to the translation if we don't want the word «commande» override «ordre» everywhere.

my two cents,
Luc
