lactase: rajout d'un nouvel item, la lactase

Cet item supprime les vents de la princesse en lui permettant
d'immédiatement digérer le lactose. Ce qui a pour effet de couper son
dash en cours et de lui vider les intestincs.

J'ai rajouté plein d'éléments dans le niveau numéro deux pour tester ça.

Addition supplémentaires:
- le fromage peut être de différentes couleurs avec pour conséquences
  différentes intensités. Ce qui a pour effet de recharger plus ou moins
  vite la jauge de pét.
 - J'ai rajouté une passerelle à sens unique qui permet de créer un
   petit point de non retour, j'aimerai bien aussi l'avoir à la
   verticale, mais pour le moment, je n'y arrive pas.
