Fixed a bug so arc editing take correctly the placement into account.
Added preliminary support for preview during arc editing. To be improved in the future.
The commit that introduces the colorization option added some problems.
First the "sectionFaceNumbers" property is only set when an execute is
performed. When this does not happen, an exception is thrown when the
document is saved that contains a fence created with an older version
of FreeCAD.
Also the new Props on the ViewProvider where not set because the
"onDocumentRestored" is not reckognized for ViewProviders.
When we set "UseOriginalColors" to true, it is possible that we cant
calculate the exact number of diffuse colors, because the "applyShape"
method optimized the shape somewhat. That operations could remove faces.
To fix this for now, we simply set the shape without further optimizations.

This commit disables an old "axis orientation correction mode", which tried to
solve a problem with orientation of the axis. It never worked fine and it should
have never been introduced, as everything it intends to do should be done by
setting the appropriate placement offset.

Points made of construction type are special non-constrainable points, such as (current) bspline knots.
This was not intended in Carbon Copy.

fixes#3974
Snapping to 45 degrees during arc creation (hold ctrl during an arc within a polyline), resulted in
reduced precision, because Gui::Command::doCommand %f defaults only to six decimal positions, which is
a poor representation in radians of, for example, 90 degrees.
A work-around could have been to hardcode a higher number of decimals, as in %0.Xf. However, I do not like
such magic numbers.
The solution chosen is to use an App.Quantity object using as units degrees, which leads to no loss of precision.
