api: ajout d’un sérialiseur pour chaque modèle

Les sérialiseurs permettent de représenter les modèles en JSON.

Tous les sérialiseurs exportent tous les champs de leurs modèles
respectifs.  En plus de cela, le sérialiseur du modèle des cours
sérialise en plus les groupes et salles pour ne pas avoir à faire trop
d’appels à l’API.
