Handling old page names+issues

Better handling of former names.

Options:

• Redirection - but what to do for inclusion?
• Do an archive search when we come to a name we don't know how to handle.  Then on the create-new-card page we offer links to all pages that formerly had that name.  That way there's less namespace hogging, more information, and still incentive to update old links. --Ethan
