#1212 partial fixed (FluidDissipation in Modelica.Fluid.Dissipation):
- Removed scripts in directory:
   https://svn.modelica.org/projects/Modelica/trunk/ModelicaTest/Resources/Scripts/Dymola/pressureLoss
  that refer to models not available in ModelicaTest
- Removed cd(".\simulation") statements in the remaining scripts and instead
  introduced calls to inquire current working directory, change to a temporary
  directory from the operating system (%temp%) and at the end switch back
  to the initial working directory.
- Run all the scripts and they seem to work properly.
