[Paraview] pqPythonShell on local server & local client

[clinton at elemtech.com]

I don't think you want to give your pqPythonShell the main window, unless 
you're using a QDialog, and pqPythonShell is not a QDialog.
Just pass in NULL as the parent of your pqPythonShell, or another QWidget you 
make yourself.

If you need the GUI Helper, you can do
vtkProcessModule::GetProcessModule()->GetGUIHelper();
