Title: jsrouting: mouseover an instruction, highlight the route segment

Nice to be able to hover over an instruction in the table and see the corresponding segment of the polyline highlighted.

I couldn't find enough docs for GraphHopper to implement it for GH. But that absence doesn't break anything.
