- Moved moderation logic back into node module.

    * After having a chat with Dries we have agreed on the logics (or
      more specifically he told me how its supposed to work). The queue
      module is just a method to make moderation public, but its not
      necessarily the only way. This brings the power back.
- Minor interface tweaks (names, case changes, etc).
- Fixed error that would show when you tried to view the profile of a
  blocked user.
