Removed call to homotopy function for issue #18
Fix for #18

Removed homotopy for sta*. Moved declaration of parameter homotopyInitialization as it is no longer used in the base classes Partial{Two,Four}PortInterface.mo. Changed line endings of PartialFourPortInterface.mo to use consistent line endings in the library.
