Refactored code to support local and external material sources
This is the first PR in a series to support external modules. External
modules allow materials to be stored in external data sources such as
databases or web services. No new functionality is introduced in this
PR, rather it is a refactoring of code that will allow for changes to
be introduced in future PRs. Minor performance improvements have also
been made in the model and material managers.
The Python API has been enhanced for many data types to allow for
modification within Python.
* Fix and add menu accelerators: menus common to all workbenches
I use menu accelerators fairly often, so I find it very frustrating when
they are missing, or worse, they don't work due to the same letter being
assigned to several commands.
This patch adds accelerators to lots of menu entries missing them and
fixes broken accelerators.
Wherever possible, standard accelerator keys are used:

This commit covers accelerator fixes that are common to all workbenches.
Accelerator fixes for specific workbenches will be done in separate
commits.

Dialogs to view the Appearance and Material properties of an object
These inspectors are intended to be used when debugging Appearance and
Material issues in a model.
The Appearance inspector displays the appearance properties of an
object. This will be more useful once PR 13792 is merged which migrates
parts to use ShapeAppearance instead of DiffuseColor. This shows each
of the appearance properties per face for the object.
The Material inspector shows the material, models, and properties
assigned to a model. It displays useful debugging information such as
the UUID and file paths associated with eacch of the items. This is
useful when finding and resolving model conflicts.
The material inspector now gives the option of copying the information
to the clipboard.
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.
Rework of the material handling system.
This first part concntrates on a rework of the material cards.
Rather than use a fixed list of possible properties, properties can
be defined separately in their own files and mixed to provide a
complete list of possible properties. Properties can be inherited.
The cards then provide values for the properties. These can also
be inherited allowing for small changes in cards as required.
The new property definitions are more extensive than previously.
2 and 3 dimensional arrays of properties can be defined. Values
are obtained by calling an API instead of reading from a dictionary.
For compatibility, a Python dictionary of values can be obtained
similar to how it was done previously, but this is considered a
deprecated API and won't support the newer advanced features.
The editor is completely reworked. It will be able to edit older format
material cards, but can only save them in the new format.
For testing during the development phase, a system preference can
specifiy wether the old or new material editors are to be used. This
option will be removed before release.
