Import Dagoma material specifications

[ubitux]

This is extracted (automatically, with a script) from the
resources/XML/xml_config.xml file installed by the Windows install
CuraByDagoma_E200_1480427910_d0965d25707767ef87c626dfbaaab4c9.zip
(dist.dagoma.fr).

Dagoma is the main distributor of these material brands.

Note: the filament_flow setting is NOT imported as there is no such
thing in the current Cura version in materials

Note: the color_code are not set

Note: the Cura UI is not intuitive with "Generic" types, you get menus
such as "brand → PLA → PLA", which is redundant.

Note: XML for materials, JSON for printers and INI for qualities looks
inconsistent

Note: actual printing untested

Comments on your notes:

• Indeed, filament flow can't be set in there. That's something we'd like to change in the future. Nothing you could do about it.
• About the colour code, that's too bad. But I imagine you wouldn't want to make definitions for all of the different colours everyone provides. We'd like to have that in the future some day.
• The "Generic" types note is related to the colour codes. The materials in those menus are intended to be an actual specific product, not "PolyFlex-but-otherwise-generic" or something. Perhaps we'll change that eventually later.
• Indeed, those three different formats is very inconsistent and we'd like to change that some day. It's a bit complicated because the materials is the worst format of them all but that one is shared with the firmware of the Ultimaker 3 so it requires some coordination.

Less the notes, this looks to be working fine. Reviewed and tested. I have permission from all teams involved to add new materials.

I could be wrong (because I don't have access to the specification), but aren't version, guid and color_code required in the specification?

[Ghostkeeper]

We recently ran into issues because the version number is missing from these files. Colour code seems to be optional. GUID I don't know. In any case, I didn't review these thoroughly enough back then, but we'll make modifications as necessary.

Cura does throw a number of warnings when displaying the materials page. But I don't know if that's the material's fault or Cura's. Is the fmdmaterial spec available somewhere?

Note: in their current state, these materials do not work very well due to Ultimaker/Cura#1496
Flexible and Wood need to have their type changed as a workaround.
