[Paraview] vtkSMProxy saving/restoring

[Nehme Bilal]

Thank you Utkarsh !

it works but I have some problems like:
- after restoring the proxy, changing some display 
properties in Paraview has no effect (like color ...)
- only the display properties are saved/restored. 
(variables in object inspector "properties" tab are not 
restored)

It's probably the way that I'm casting the source proxy 
and some staff like that.

I'll try to solve these problems and let you know.

thank you !
