princess/saut du mur: prise en compte du feedback

avant jouer au clavier, c'était impossible. Voic les améliorations:

- une fois que le joueur a décidé de se coller au mur, on le laisse
  collé tant qut'il ne décide pas d'en partir volontairement.
- j'ai rajouté des ray_cast à la tête et aux pieds de chaque côté pour
  que l'on puisse continuer de wall jumper jusqu'au bout
- si au cours d'un dash ou d'un kick on s'écrase contre le mur, la
  princesse s'y colle toute seule.
- faire flèche du bas permet d'accélérer la chute.
