feat(editor): the vertical profile shows the terrain model, the terrain follows it, the camera follows the plot

Browse Source 
- The plot draws the ground of the terrain model (NMT) as measured, before any earthworks. The squares under the route are fetched in the background. The tooltip gives the grade line's distance from the model.
- Applying a profile lays the formation of the changed tracks anew, or reshapes the route's earthworks when there are any, so the heightmap terrain follows the new grade line. The terrain step is joined to the track step: one undo takes both back.
- In 3D and in the top view, the camera shows the part of the route the plot shows once the plot stops moving. It keeps clear of the floating plot window. A toggle turns this off.
- nmt_shape_tracks can shape only the given tracks, removing the modifiers of their paths that are gone.
