Accepting request 287947 from home:dkxls:cfd

The proposed changes compile VTK with MPI support.

Considering that pretty much any computer nowadays has several CPU cores it just makes sense to enable parallel computation support for a toolkit like VTK.

The changes are small and straight forward. I tested the serial and parallel versions (vtkpython and pvtkpython) and both work as expected.
