French translation

Hello,

I’ve noticed a wrong French translation for “Previous post” -> “Article précédent” with an “e” not an “a”
It is in the fr_FR.po file

#: ../lib/custom.php:416 ../templates/entry-post-links.php:3
msgid "Previous Post"
msgstr "Article précédent"

Another problem in the contact page, two error messages are not translated. It is in the plugins/virtue-toolkit/page-contact.php file, lines 13 and 14

required: "<?php echo __('This field is required.', 'virtue-toolkit'); ?>",
email: "<?php echo __('Please enter a valid email address.', 'virtue-toolkit'); ?>",

The French translations could be “Ce champ est obligatoire.” and “Merci de saisir une adresse email valide.”
