Validate only one file by Name

[sureshhewabi]

here's a good reason why we need to be able to only validate one mzid file by name in a complete: -rw-rw---- 1 pride-drop-005 pst_int 138M Jan 19 20:41 2017_Fusion_DDA_SwissProt_results.mzid -rw-rw---- 1 pride-drop-005 pst_int 504M Jan 19 20:47 2018_QEHFX_DDA_SwissProt-MAJIQ_results.mzid obviously one would like to provide the 138M mzid for validation not the 504M one but since it was done with Proteome Discoverer I would prefer by default to try to validate it to check not skip it altogether

This idea originally proposed by Atilla. But I don't think this is a need now. We can implement this when we have a usecase.
