feat(editor): the free ends of the tracks are marked red in the track mode

Browse Source 
Each end of a rail track joined to nothing, where a train would run off, gets a red dot next to the white dots of the joints,
in the 3D view near the camera and from above over the whole view. The ends are looked for again after an edit or once the
camera leaves the place they were found for, not every frame.
