We're starting to see developers use subkeys of their primary key to
sign packages, which we aren't handling well in the web interface. These
subkeys show up as unknown, which isn't strictly true. Start the process
of being able to handle these keys by adding a model that will store all
known keys and subkeys and the relationships among them, as well as
which developer owns each.
