        """Modifie la stat d'un personnage.

        Cette action doit être de préférence utilisée pour augmenter
        les stats d'un personnage. Pour consommer des stats particulières
        (comme la vitalité ou l'endurance), utilisez l'action
        'consommer'.

        Paramètres à préciser :

          * personnage : le personnage dont on veut modifier la stat
          * nom_stat : le nom de la stat
          * valeur : la valeur de la nouvelle stat

        Exemples d'utilisation :

          changer_stat personnage "force" 90
          changer_stat personnage "vitalite_max" 2000
          changer_stat "mana" 80

        Note : n'utilisez pas cette action pour tuer un personnage
        (utilisez l'action 'tuer' pour ce faire).
        Si vous voulez modifier la stat max d'un personnage, utilisez
        "stat_max" (par exemple "vitalite_max"). Notez que les noms
        des stats sont en minuscule et sans accent.
