Martin Pepin d6dd7b346c Merge branch 'Elarnon/mail_bda' into 'master'
Améliore les mails automatiques du BdA

Les mails du BdA sont maintenant tous chargés depuis des templates gérés par le système de templates de Django, et plus par de l'interpolation de chaîne de caractères. Ceci permet en particulier d'utiliser (et de configurer) la localisation de Django afin d'afficher les dates de façon uniforme (et sans "hack" à la `date_no_seconds`) dans un format comportant un "à" entre le jour et l'heure.
