  This file defines the main menus and the pop-up menu (right-click menu)

  There are 4 menus that have to be rebuilt everytime there are called:
  Audio, Video, Navigation, view
  4 functions are building those menus: AudioMenu, VideoMenu, NavigMenu, View
  and 3 functions associated are collecting the objects :
  InputAutoMenuBuilder, AudioAutoMenuBuilder, VideoAutoMenuBuilder.

  A QSignalMapper decides when to rebuild those menus cf MenuFunc in the .hpp
  Just before one of those menus are aboutToShow(), they are rebuild.
