enable/disable uturns at via points

[DennisOSRM]

a right click on via points should do this

[TheMarex]

Right click is not really good in a browser (as it is mapped to context menu). You mean left-click?

[DennisSchiefer]

The previous frontend used left clicks to delete markers.

Maybe use a js context menu to invoke such specialized commands?

[TheMarex]

Hm, popup on the marker + some buttons will probably do the trick.

[TheMarex]

Adding uturn support to LRM has some unforeseen design implication. Will need some smaller refactoring on the LRM side.

Fixed with commit cb0d056.
But adding &u=true after the waypoint does not seem to do anything for me here. @DennisOSRM ?

The github demo site should be recent.
