Change trending hashtags to be affected be reblogs (#16164)

If a status with a hashtag becomes very popular, it stands to
reason that the hashtag should have a chance at trending

Fix no stats being recorded for hashtags that are not allowed
to trend, and stop ignoring bots

Remove references to hashtags in profile directory from the code
and the admin UI
