Aurélien Delobelle 49bb7d99cd Modification de l'enregistrement sur K-Psul
- Passe le calcul du montant d'un achat dans la vue au lieu du clean du
  form
- Corrige le calcul d'un achat et le calcul total du montant de la commande
- Ajoute l'enregistrement du statut COF de la personne associée à la
  commande

La subvention COF, la majoration possible (type concert), autres...
devront être prises en compte donc le calcul d'un achat doit être dans
la vue.
Les achats et les retraits doivent avoir un montant négatif tandis que
les charges ont un montant positif.
L'enregistrement du statut COF servira aux futures statistiques.
