cubicweb #1546397 [i18n] translations of login actions in french [validation pending]

in the top right corner of http://www.logilab.org when browsing in french, I see "s'authentifier" and "s'enregister", and if I click on the first, the button used to validate is labelled "s'identifier". I feel that the button and the link should have the same label.
