[Paraview] How to add plug-in's parameters to ParaView state file

[Utkarsh Ayachit]

Nenad,

The signals that pqApplication core fires are actually forwarded from
vtk-events fired by the proxy manager (look at
pqApplicationCore::onStateSaved/onStateLoaded). So you can add an
observer to those events on the proxy manager from Python and handle
them. However, you cannot really processes the arguments passed to
when the event  is fired in Python. One workaround would be to create
a vtk-class that does the event handling and simply instantiate and
initialize it in Python.
