- Remove demo/icons/Logos.qrc, replaced by demo/resources/CGAL.qrc, that

also contains :/cgal/help/about_CGAL.html
- Add include/CGAL/Qt/debug.h and src/CGALQt/debug.cpp, that will contain
  debug tools/functions. For the moment, they just define:
      void traverse_resources(const QString& name);
  that must be used like that:
      CGAL::Qt:traverse_resources(":/cgal"); // view CGAL resources
  or
      CGAL::Qt:traverse_resources(":"); // view all resources
  and displays the resources tree on std::cerr.
