Double-clicking Intersections seems to break the RoadBuilder plugin.

[awenonian]

On the courier-functionality branch, if you double click on an intersection to toggle it between intersection and dropoff, the RoadBuilder plugin becomes unresponsive. e.g. Clicking does not add new points, clicking and dragging on intersections moves the whole roadmap.

Have a fix for this. Just waiting on merging current outstanding branches so this can be handled cleanly.
