feat(editor): the tracks onto the terrain from the terrain panel too: the terrain model (F5 Terrain) has a step 3, Tracks and terrain, with Tracks onto the terrain, the one to take first, big, what it does told under it (all the tracks go down or up onto the model, loaded along them by itself), then, after "Or:", Only the ones not fitted and Terrain under the tracks, each with a line of the case it's for; the same block stays in the panel of the tracks, under All the tracks of the scenery, with a line saying where the scenery is put on the map while it isn't. The progress of these is shown at step 3, the loading buttons of step 2 greyed meanwhile. The terrain lesson of the tutorial tells of step 3 so
