Webplanner - route history duplicate entry

Hi

Great to see Route History (Undo/Redo) in the Web Planner!

I came across a minor issue regarding the handling of insertion boxes in the itinerary. The design seems to be that these are all first removed before an undo or redo is executed which then acts on real points. However if you do the following sequence it isn't consistent:

Create a route with a few points.

Do an 'undo' - last (real) point is removed.

Then create an insertion box anywhere in the route using the itinerary.

Do an 'undo' - the insertion box gets removed, but no action on any real point - which is unexpected.

Do a redo - nothing happens.

Do an undo - nothing happens.

Do an undo - last point is removed.

Do a redo - point re-added

Do a redo - nothing happens

etc.

Seems that a duplicate entry has been added in the history stack, which happens when you add an insertion box after already having done an undo.
