[Paraview] Programmatic interaction with the colorScalarBar

[cunrein]

I am using ParaView3.4.0 with Qt4.5.0.  I have solved the 3 
colorScalarBar issues, but I still have the timer hack in place.  Are 
there any pq/qt triggers available that will tell me when a new 
pipeLineRepresentation has been added?

Thanks, Chris
