Cinema: Incorrect naming of columns for Spec D table
When exporting a Cinema Spec D Table, ParaView and Catalyst output a csv file that has a 'FILES' column. According to the specification, this should be named 'FILE' (no 'S').
Example: phi,theta,FILES 10.0,10.0,filename.png
Should be: phi,theta,FILE 10.0,10.0,filename.png
