Essais des méthodes concernant la souris (sera utile pour zommer dans la représentation graphique).

Attention : 
- penser à encadrer tout code souris par #ifdef NCURSES_MOUSE_VERSION (car pas portable)
- pas d'event de déplacement de souris sans clic
- pas de surbrillance curseur sous xterm et compagnie
- pas de souris par défaut en tty1
- la souris donc doit être non nécessaire (trouver une bonne idée ergonomique pour zoomer la représentation graphique et dire à quels secteurs on est...
