Subject: [PATCH] Ajoute un switch sur les tirages
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Le switch permet d'autoriser/interdire le lancement d'un tirage. Il
s'agit d'une sécurité face aux erreurs d'inattention.

Le champ `token` du modèle `Tirage` devient `tokens` et stocke les
graines des tirages déjà lancés si le tirage est lancé plusieurs fois.
