[Paraview] Generating an animation in Paraview 3.2.1 ( vs. Paraview 2.6 )

[Berk Geveci]

This is fixed on cvs head. I am also attaching a patch in case you
want to apply it to your 3.2 source. The patch has to be applied in
the ParaView3/Servers/ServerManager/Resources/ directory. The patch
only adds support for animating stl file series. We do not support
file series of formats that natively support time such as XML-based
VTK formats. To animate those, you have to write a pvd file.
