Add Nickname to profiles listing page

[kmoorhead]

Sometimes a profile will have multiple URLS from different domains. On the profile page it lists the first domain's name. Which makes it hard from the profiles page to determine what each profile if for. When I set up a profile, I put a nickname in the Notes tab so I refer to it later when I need to make changes. However, it would be nice if we could add a nickname or comments column to the profile listings page so we could add nicknames, notes, etc.
