Noah Petherbridge 28d1e284ab User Forums: Newest Tab, Moderators
* The "Newest" tab of the forum is updated with new filter options.
  * Which forums: All, Official, Community, My List
  * Show: By threads, All posts
  * The option for "Which forums" is saved in the user's preferences and set as
    their default on future visits, similar to the Site Gallery "Whose photos"
    option.
  * So users can subscribe to their favorite forums and always get their latest
    posts easily while filtering out the rest.
* Forum Moderators
  * Add the ability to add and remove moderators for your forum.
  * Users are notified when they are added as a moderator.
  * Moderators can opt themselves out by unfollowing the forum.
* ForumMembership: add unique constraint on user_id,forum_id.
