With PR #14460 the "machinability" model was introduced. As sample data
the legacy material cards from the "feeds and speeds" addon were added
and (partly) converted to the new format. However, due to copyright
concerns and unclear semantics of the data, the values required for
cutting force calculations have been removed.
This commits adds material cards with complete machining model data
for various classes of metals. The data comes from the German standard
work "Tabellenbuch Zerspantechnik", ISBN 978-3-7585-1315-2, 5. Edition
2022, http://www.europa-lehrmittel.de/14733
Usage of this data for our purpose is legal as facts are not protected by
copyright according to German law. This view has been confirmed by the
licensing department of the publisher.

* Draft: Fix cursor scaling
The get_cursor_with_tail function was rewritten to match the Sketcher cursor code. Hopefully this fixes the scaling issue.

@maxwxyz
Can you check if this code fixes the issue? Apart from the size the 'hot' pixel should be checked. If you approach a vertical line from the left or right it should get highlighted at the same distance.

* [DraftBind] Bug-fix Consecutive Face Touch at Corner
Update following commit at https://github.com/FreeCAD/FreeCAD/pull/15350
* Minor formatting changes
coding_conventions.md says variable_names_without_capitals
* Use areColinear to find problematic edge pairs
It is clearer to use `areColinear` instead of `findIntersection` to detect problematic edge pairs.
@paullee0 Please check. Thanks.
* Use Shape.section() to find touching edges
Using `areColinear` indeed does not work here.
But the `findIntersection` function is very confusing IMO. It finds intersections for collinear edges which does not make sense.
Let's use `Shape.section()` instead.
Also improved the 'ascii art' a little.

* Typo
* [DraftBind] Bug-fix Consecutive Face Touch at Corner
Further update handling closed wire(s) case :
# if wires are closed, 1st & last series of faces might be connected
# except when
# 1) there are only 2 series, connecting would return invalid shape
# 2) 1st series of faces happens to be [], i.e. 1st edge pairs touch
