[Paraview] Reader has Filters Disabled`

[Brian C. Panneton (CONTR)]

Everything in the information tab does look correct. (Sorry I forgot to 
mention that I switched from PolyData to UnstructuredGrid earlier). 
Basically everything works as it should, but I don't have the option to 
use the filters on the data.

With:

Type: Unstructured Grid
Num Cells: 159
Num Points: 159

I figured I would have at least a few filters. Or after I selected a few 
points some filters would show up.
