feat(editor): the tracks are laid to the PKP PLK norms only: the choice of the free laying is gone, its cards in the panels of the laying and of the plan, the question as the laying starts and the setting; the transition curves and the cant of the norms always, the speed of the laying with its chips, the radius below the minimum for the speed a warning. The settings keep the radii the bends of the straights will be eased with instead
