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.

Intended for use wherever an active body is needed but none exists. The dialog
contains a list with the bodies present in the document, with an extra option to
make a new body. Custom text can be provided if needed.
This commit also replaces the warnings used by "new sketch" and "primitive"
command with this new dialog.

(I see the same is already done for Mesh.)
With the recently introduced AttachExtension the PartDesign primitives can be attachable by themself and don't need anymore the helping coordinate system datum. This simplyfies the code and the TreeView largely
