comm.json should show role

[kmccurley]

I've noticed that some people put a name with (co-Chair) in the name file of the comm file, because we have no way of representing different classes of members in the program committee. We know that chair and co-chair exist, but there may be other types in the future like "senior chair" or "advisory chair". For this reason we should have a field for role, and show whatever text is entered there next to the name.

The reason we need this is that I now fetch the comm.json file to insert into the program committee table on cryptodb. If I can't match the name and role, then it's difficult to match up to the database.
