ParaView binaries weren't using packaged Python.

The problem was that the Py_SetProgramName() wasn't being called when expected.
That was resulting in Python not trying to look for Python packaged with
ParaView and hence the binaries were failing. This should fix that problem.

Change the behavior for splash screen, default off.

The splash screen is now off by default. Users can change this behavior
from the settings dialog. paraview.exe -dr should not popup a splash
screen anymore.
