Add a rule under page and post titles, and tags shown with a # in front

Two Design tab options in the Posts section. The title rule reuses the
header rule's kinds (line, dots, stripes): a body class blog.css draws
from — width and style only, so the theme CSS's link colour is not reset —
ending at a floated thumbnail instead of running under it. The tag hash is
applied everywhere tags are listed: under posts, in both tag modules and in
the tag page's title.
