Reimplement the ability to use drag & drop on the map view to move the start / destination points or reorder intermediate route points
Version 46's reordering of intermediary route points within the sidebar works, but you can't do that within the vector map view.
We should be able to move any start/intermediate/end point by dragging them to another location on the map, which would then make the itinerary recalculate itself accordingly.
While hovering points on the map, it would be nice to visually highlight the corresponding point in the directions sidebar, too.
