Add RotationalStiffness (#414)

* Added RotationalStiffness unit

* Updated format, changed XmlDoc to link to wikipedia, updated abbreviation to correct syntax. Added operators to get torque from rot stiff and angle, angle from torque and rot stiff and rot stiff from torque and angle

+//     Whenever a new unit is added to this quantity and \generate-code.bat is run,
+//     the base test class will get a new abstract property and cause a compile error

+//     See https://github.com/angularsen/UnitsNet/wiki/Adding-a-New-Unit for how to add or edit units.

+//     Add CustomCode\Quantities\MyUnit.extra.cs files to add code to generated quantities.
