Subject: Entry single pages: handle permalinks gracefully, populate with
 attribute.

* A single page is generated from the single-page attribute on <entry>
  element (stored in database as do_single_page).

* Permalink refers to the single page.  Same from weblog index.  Other
  links are subject to debate (e.g., what about internal links? now we
  link to single page when link has a supplement part, but this is
  debatable).
