Bug#692943: status of mentors.d.n data in UDD

[Lucas Nussbaum <lucas@lucas-nussbaum.net>]

Hi,

I made some progress on importing mentors.d.n data in UDD. Rather than
importing the Sources file, I imported the SQL data directly, in
mentors_raw_* tables, providing a mentors_most_recent_package_versions
view for convenience.

I built a CGI that demonstrates what can be done:
http://localhost/udd/cgi-bin/mentors.cgi

Paul, you suggested to import Sources file. Do you have a use case that
requires Sources to be imported, or do you think that we can close
#706678?

Two remaining things to do:
- leverage that in dmd.cgi (#692943)
- improve the cgi with filters similar to the ones on bugs.cgi.

Any takers? :)
