items/fromages: la princesse peut manger un fromage

En vrai, pour l'instant voilà ce qui est fait:

- le fromage existe et est plaçable sur le niveau à convenance. Autant
  qu'on veut.
- le fromage est une entité autonome dans ses animations et c'est lui
  qui va enoyer un signal à la princesse quand elle rentre en collision
  avec lui.

 Reste à mettre en place:
 - Un timer pour faire réaparaitre le fromage
 - Un affichager de jauge à prout pour la princesse
