When matching, ignore 'is_startpoint' propert, snap to any edge (#5297)

Browse Source 
Includes all edges in the rtree, but adds an `is_startpoint` flag to each.  Most plugin behaviour remains unchanged (non-startpoint edges aren't used as snapping candidates), but for map matching, we allow snapping to any edge.  This fixes map-matching across previously non-is_startpoint edges, like ferries, private service roads, and a few others.
