@*
	Les deux menus d'un véhicule, à droite de l'écran (on garde la voiture en vue) :
	- le coffre (E derrière la voiture, déverrouillée) : les poches d'un côté, les cinq
	  emplacements du coffre de l'autre ; un clic fait passer une pile de l'un à l'autre ;
	- la gestion du staff (G, au volant ou en regardant un véhicule) : réparer, remettre sur
	  ses roues, verrouiller, couper le moteur, ranger.
	Rien n'est décidé ici : chaque bouton est une demande à l'hôte.
	Ajouté au HUD par VehicleManager à l'exécution (pas dans la scène).
