Code review comment for lp:~jcsackett/launchpad/unknown-blueprints-service-597738

The UI changes look good to me, although it's confusing that the new template (lib/lp/blueprints/templates/unknown-specs.pt) uses the term "specification[s]" when the rest of the page uses "blueprint[s]". I think we should use only one of them, and most likely the preferred would be "blueprint[s]" as that's what is used in the top heading.
