[vtkusers] Choosing time for vtkOpenFOAMReader

[David E DeMarle]

In vtk 6.3 it was:
anAlgorithm->UpdateInformation();
anAlgorithm->SetUpdateTimeStep(0.5);
anAlgorithm->Update();
Try that.

In vtk 7.1 it is:
anAlgorithm->UpdateTimeSep(0.5);
Since Berk cleaned up the parts of the pipeline that caused issues like you
are seeing.
