Improve french translations

The current fr locale generated errors like "Le email est obligé" which
is just wrong. Even if we correct into its probable original meaning so
it becomes "est obligatoire", the fr-CA/fr-CH wording is much more correct.

Then there's the gender problem which is also present in the fr-CA/fr-CH
locales, by removing the gender we avoid the pain of writing an error
message like "Le/La/L' {field} {message}".
