improved route description (added distances to the right, bold street names, orientation in first instruction and non-breaking spaces for units), route link now displays the shortened link name, content of input boxes is only overwritten if the respective node is set or dragged, experimental support for reverse geocoding (when setting a new node by text box or clicking on map)
