feat(editor): the data of a track under the cursor give its grade there and its cant, and the radius of a curve without one written

Browse Source 
After the cursor rests on a track, its label gives the grade at the place pointed at and the cant of the path, besides the
name, the length, the radius and the speed; a curve whose radius isn't written in the scenery gets the one of its geometry
instead of being called straight.
