In v0.22 a version number -1 is added to the material files to distinguish between old and new project file.
But v0.21 doesn't know about this version number and interprets it as number of elements instead.
Because this value is assigned to an unsigned type the value becomes 2**32 - 1. Now trying to create a container of this size requires > 280 GB
of RAM. On most systems FreeCAD new handler will jump in and raises a memory exception to stop the allocation. But an other systems with
plenty of RAM it's tried to allocate the memory and then may crash at some point.
This PR fixes this regression. It puts the version number to the MaterialList XML element as an optional attribute.
With this change FreeCAD v0.22 is still able to load projects that have been created prior to this change.
Additionally FreeCAD v0.21 can again load project files without crashing.

Creating a shape with Part.CompSolid(), Part.Compound() or Part.Shell() is a null shape. In order to allow to append sub-shapes with the add()
method a valid shape must be created beforehand.
This fixes#13208
* Gui: Rename NavigationStyle::pan to setupPanningPlane
* Gui: Replace duplicate code with NavigationStyle::setupPanningPlane
* Gui: Use panning plane when hit point not found in lookAtPoint
Also enables navigation animations when pressing MMB while the mouse is not over an object
* Gui: Remove unused methods
The underlying problem is the method DocumentItem::updateItemSelection() where
the selection is altered. This may cause the destruction and recreation of the
DocumentObjectItems so that the passed pointer can become dangling.
The issue is fixed in two steps:
1. Add the method 'DocumentObjectItem *findItem(App::DocumentObject* obj, const std::string& subname) const'
to safely re-access the item.
2. Add a boolean flag 'dirtyFlag' and the methods insertItem() and removeItem() to DocumentObjectData.
This is needed to check when the iterator over the container becomes invalid.
