[HydrolienF]

• press space key should go to next Dialog frame if it's possible.
• clicing everywere on frame should go to next Dialog (not only on map) (It have been broque when PanneauSup have been place under all button.
• It can be done by creating an other PanneauSup only for Dialog (it will listen clic & if !=null listen space)
• We only need to setSizeMax() at every new Dialog with skip button & setSizeMin() when it have been clic / space press.
• fix InputMap that don't catch key.
