Tpac: better "HTML view" for shared lists under "my lists"

From the "my lists" interface, you get a link labeled "HTML View" for
any shared lists, and this link, while meant to be shared, just
gives you a search results page where the only search term is simply "in
the given list."

This commit makes the search results page a little smarter in that case,
in order to
    a) show you the bookbag metadata, including name, description and
        item notes.
    b) allow you to keep searching *within* your list, until you don't
        want to anymore, at which point there's a checkbox you can uncheck.
