feat(editor): switch templates for the rail of the selected track, their names translated, shorter hints

- the template list shows the templates of the rail the selected track is laid with (railprofile s60/uic60: 60E1, s49:
  49E1, s42: S42), a box shows them all
- the words of the catalogue names are translated (movable nose, long, gauge, blades outside), the kind of a slip or a
  crossing its type says already is left out
- shorter hints of the switch tool, of More and of the missing drives
