The view2.5D extension does not handle shape changes

[brandesNW]

In view2.5D extension if a shape is created, edited, deleted or imported no corresponding action happens in the 3D view.
Shapes can be turtle or link shapes.

Except in the case of editing a shape, an uncaught exception occurs.

To reproduce the bug.

Create a model that includes the following code

extensions [ view2.5d ]

to setup
  view2.5d:remove-all-turtle-views
  view2.5d:remove-all-turtle-views

  view2.5d:turtle-view "Test" turtles [ the-turtle -> [3 +  abs xcor] of the-turtle ]
  wait 1
  view2.5d:set-observer-distance "Test" 40

  view2.5d:set-z-scale "Test" 2
  view2.5d:set-observer-angles "Test" 25 30
  ;; increase the stem thickness
  view2.5d:set-turtle-stem-thickness "Test" .2
  view2.5d:update-turtle-view "Test" turtles
end

to create-ambulance
  create-turtles 1 [ set color orange set size 4 set shape "ambulance" setxy -2 3]
  view2.5d:update-turtle-view "Test" turtles
end

The model in the attached zip file can be used to test the changes.
Follow the steps from top to bottom.
For steps that require editing, creating or importing turtle shapes, use the Turtle Shapes Editor.
Changes to turtle shapes should be visible in the Turtle View, Patch View and the 2D view.

Note: all links appear as cylinders, so no testing of link shapes is required.
