    Use a caching stream for popular notice section

    Instead of a big cached query, we now use a caching notice stream for
    the popular notice section. It uses a single-table query at the
    bottom, then scopes the notices and filters for silenced users. This
    should be much nicer to our database servers.

    Also clears the popular cache when someone favors or disfavors
    something. A nice optimization would be to save the last weights and
    re-calculate them at invalidation time, adding the new notice (or not)
    depending on its own score. That will have to wait for another day,
    though.

    Let CachingNoticeStream users skip the ';last' optimization
