* All users can now view deleted posts.

* Posts now have an is_banned flag for artist removal requests.  Basic users can not view banned posts but gold and higher can.
* Banning an artist both deletes the post and bans it.
* By default deleted posts are not filtered out of post searches at the sql level.
