- Add missing Property classes for all Units
- Add missing units to unit calculator, as well as some missing string representations
- also change units used for dynamic viscosity to the customary Pa*s
- is not feasible for practical usage and (was up to now not used, thus no consequence)
moreover, Oersted is a cgs unit while we use SI units, thus also not suitable for FEM, only makes problems for magnetization
This undoes a small part of commit 5de761eef0cb059c899fd6388dc2a5f88e40f526,
which seems a bit too agressive. Without the cmath header the build fails
using Apple clang version 11.0.0 (clang-1100.0.33.17) on Mojave with the
following error:
.../FreeCAD-git/src/Base/UnitsSchemaInternal.cpp:39:24: error: call to 'abs' is ambiguous
double UnitValue = std::abs(quant.getValue());

- fix message that permittivity object was not handled
- set an expression, otherwise the user gets only "0.000" for the default of 8.8e-12
- use as unit the common "F/m" (this is also more user-friendly than "s^4*A^2 / (m^3*kg)")
- fix a ToDo
Contrary to any other Unit with micro prefix (e.g. ug, uH, uF) the
string was created with a Latin1 encoding instead of UTF-8.
The problem can be verified with these python statements:
```
FreeCAD.Units.schemaTranslate(FreeCAD.Units.MicroSiemens, 0)
FreeCAD.Units.schemaTranslate(FreeCAD.Units.MicroGram, 0)
```
- this is necessary to perform electrodynamics simulations. Since the typical values are in the range of 1e6 S/m, we need the new units kS and MS
- since this is for simulations, also add electrical conductivity to the FEM material cards

Independent of scale, use only mm/min or in/min because it is compatible
with GCODE feed rate units.
(My use case is definition os feed-rates in PathLoadTool.py).
