Amélioration gestion des relevés

Nouveau relevé:

Il faut donner le détail du nombre de chaque
  pièces/billets pris et laissé en caisse pour calculer les valeurs
`balance_new` et `amount_taken` d'un relevé (`CheckoutStatement`).
L'erreur est directement calculée par rapport à la balance actuelle de
la caisse et ces 2 valeurs. Une erreur positive correspond à un surplus
d'argent et inversement.

Modification d'un relevé:

Il est possible de modifier les infos d'un ancien relevé. L'erreur est
ensuite recalculée à partir de ces infos.
Important: Dans le cas où `balance_new` est modifiée et qu'il s'agit du
relevé le plus récent sur cette caisse. Alors la balance de la caisse
est mise à jour en prenant en compte cette correction (et en conservant
les modifications s'il y a eu des mouvements sur la caisse)
