For bitbucket issue #2, tweak the admin settings for the Post model to
reduce slow queries. Define our own queryset() method so we can control the
select_related(), and not have it cascade from post to topics to forums to
categories. Removed 'topic' from list_display because MySQL still sucked with
2 inner joins. Now it seems to be tolerable with only one join to User.
