- routers/user: little code format
- conf/locale: update French locale

- templates/user/settings: fix email panel nav highlight

Also, change all current 'emails' to 'e-mails'.
Still todo: some CSS for the user/settings/email page, but that is not my specialty

All basics are implemented. Missing are the right (localized) strings
and the page markup could have a look at by a frontend guy.
