Improves the use of the ShapeAppearance property for the Part workbench.
removes DiffuseColor property
adds Python compatibility using custom attributes
transitions DiffuseColor to ShapeAppearance on open
Improved UI elements for setting object appearance, and appearance per face
Lays the foundation for future texture support
Uses new material system for appearance
Each feature object now has a property called ShapeMaterial that
describes its physical properties. If it has a shape, it has a
material.
The ShapeColor attribute is replaced by a ShapeAppearance attribute.
This is a material list that describes all appearance properties, not
just diffuse color. As a list in can be used for all elements of a
shape, such as edges and faces.
A new widget is provided to allow the user to select materials in a
consistent fashion. It can also launch the material editor with its
more advanced capabilities.
* Maybe you meant to call Primitive::onChanged() instead [-Wclazy-skipped-base-method]
* Maybe you meant to call Primitive::mustExecute() instead [-Wclazy-skipped-base-method]
* Missing reference in range-for with non trivial type [-Wclazy-range-loop-reference]
* Use multi-arg instead [-Wclazy-qstring-arg]
* Use midRef() instead [-Wclazy-qstring-ref]
Replace the int of the 'resolve' argument of several functions with a proper enum class.
* This avoids the inconsistencies in client code where often true/false is passed when an int is expected
* This avoids the use of magic numbers like 0, 1, 2 or the undocumented 3
* [Part] feature to make persistent section cut views
* one aim is to have a feature to make real cuts, not hollow ones like with clipping
* the second one is to have a persistent view, so an object in the tree that can be further exported, meshed etc.

According to the source this command was deactivated until issue #0477
and hence #1954 could be solved. However, since those issues
haven't been addressed the command has remained hidden for a long time.
This command does not work with objects that reimplement
their edit modes, meaning that it may work with Part and PartDesign
created objects but not with Draft and Arch objects.
The command is added to the standard `View` menu,
and to one `Part tools` toolbar so that it is no longer hidden.
The limitations of the command can be described in the documentation,
and then somebody else can help solve the problem
with the edit modes.
A new icon for the command is also provided.
Also update the text of the buttons in the `TaskDimension` task panel.
Remove tabs in the source code, as there was a mix of tabs
and spaces. Further cleaning is necessary as the indentation
is inconsistent and mostly 2 spaces instead of 4 spaces.
The previous icon was improperly trimmed. The new icon
shows the projection more clearly as one object imprinting itself
over another.
Also update the tooltip, fix the indentation of the code,
and the title of the taskpanel `DlgProjectionOnSurface.ui`.
The path to the icons is added to `AppPartGui.cpp`
using `Gui::BitmapFactory().addPath()`, so the icons are found
automatically in their new directories.
