Continues the work of the material subsystem improvements.
This merge covers the continued development of the material editor. The
primary improvements are in the handling of 2D and 3D array properties.
These properties are now fully editable, and can be saved and restored.
The cards now separate the author and license. These were previously
saved as a single item. Future support will be provided for standard
open source licenses.
Saving operations validate the cards to ensure UUIDs of materials are
considered. Warnings are given when a save could potentially impact the
models, such as saving over a material instead of creating a new
instance.
The editor is still not complete. There are a number of functional
elements, such as drag/drop operations, folder creation, and deletion
operations that need to be added to the main tree. State needs to be
saved and restored to improve the user experience. The appearance
preview also needs significant work. This will be handled in a future
PR.
Update Python tests to work with other locales
This fixes issues #10917 and #10924
Numeric values were beign compared to strings that did not take into account localizations. The test was modified to work regardless of localization.
There is still a known issue when working with pt_BR.UTF8. The default encoder for this localization is not UTF8 resulting in an error working with a parameter that returned the UTF character for the Greek letter mu in its units.
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.

This PR fixes the long-standing major bug that for languages using ',' as decimal separator the material editor was useless. (bug no. 10 in https://forum.freecad.org/viewtopic.php?t=56912)
the issue was that the value was handled as text. This PR:
- using a spinbox instead if a text edit to modify numbers (has also the advantage to be able to change values by spinning)
- sets min/max properly for all number data types
- also avoid rounding artifacts when changing Float values
- handle case that material cards are chosen from folders outside of the standard material folders
- also reduce singleStep size for spin edits for more convenience
- the material editor failed for Fluid materials because this info was not passed to it. Instead always solid materials were loaded.
- also fix warning about too long variable name and remove unnecessary debug code
- at the moment you get several warnings about missing icons when starting the Material editor
The reason is that they are not registered in CMake
- also remove icon from Material icon editor. As it is a child of FreeCAD it should have the same FreeCAD icon as all other FreeCAD widgets.
- also fix warning about too short variable name
- uses the constraint for 2D magnetodynamics to perform e.g. Elmer's tutorial non. 15
- modify the Material manager to get rid of magnetization but keep the vectorial functionality because in future there will be support for e.g. birefringence materials etc.
- for electromagnetics we have vector fields and thus need to specify components
- as first step use the new material "Magnetization"
- also get rid of annoying debug messages output on normal use in the material dialog
- this fixes a mistake from commit 821dc915
- it also consistently use the thermal expansion coefficient
- add code comments
now the material task dialog works with all fluid materials without errors or warnings
- since a while ThermalExpansionCoefficient is used, VolumetricThermalExpansionCoefficient is only used for the material task panel
- as already stated in a code comment, the unit of VolumetricThermalExpansionCoefficient is ThermalExpansionCoefficient, therefore we must check for ThermalExpansionCoefficient
- we must also check if ThermalExpansionCoefficient exists
- Adapt the existing fluid material cards to use the ThermalExpansionCoefficient
