ModelicaTest.MultiBody.Parts.PointMass has been changed in MSL 3.2.1 by providing different initial conditions. This gave a regression failure. Changed the initial conditions back to the one from MSL 3.2.
Furthermore, moved package Rotor1D to the end of this package (that otherwise consists only of models).
