[Paraview] Make array calculator operate on field data AND Field data is not maintained after some filters

[Felipe Bordeu]

Hello,

I work mainly with XDMF files in ParaView in a daily bases, and I 
normally add some field data to store global data (like material 
properties or extra model parameters).

The problem:
1) Some filters like the 3D filter do not pass the field data to the output.
2) I need to calculate some quantities using the field data and point 
data, so I need to have access to that data in the calculator.

I patched my version of ParaView (3.14 Linux 64) and put the code in the 
bug tracker 6 months ago, but nobody seems to care about it.

Please can someone look at the patches and tell me if is the good 
approach. And eventually commit the patches to the ParaView repository.
