Adding connecting info between combined result tables

[roberthardt]

Dear developers,

would it be feasible to include unique row identifiers which link information in the various combined_* results tables? This way one could look up relatively easily connected information e.g. find the peptides belonging to one protein or to a quantified phosphosite. I think MaxQuant does it this way having a numeric ID column per result table type.

Best regards and thanks again for the awesome software you provide for the community.
