This patch updates the french translation. Of notable interest: - all 897 messages are translated - no fuzzy messsage remains
I have not reviewed all messages, just those that were not translated, and those that were fuzzy. I did spot a few errors that I fixed. Also, in French, the correct translation for 'scanner' is 'num?riseur', but is not widely used, and we do use 'scanner'. I have changed two occurences of 'num?riseur' back to 'scanner'.
