Finish Forums + Likes & Notifications

Finish implementing the basic forum features:
* Pinned threads (admin or board owner only)
* Edit Thread settings when you edit the top-most comment.
* NoReply threads remove all the reply buttons.
* Explicit forums and threads are filtered out unless opted-in (admins
  always see them).
* Count the unique members who participated in each forum.
* Get the most recently updated thread to show on forum list page.
* Contact/Report page: handle receiving a comment ID to report on.

Implement Likes & Notifications
* Like buttons added to Photos and Profile Pages. Implemented via simple
  vanilla JS (likes.js) to make ajax requests to back-end to like/unlike.
* Notifications: for your photo or profile being liked. If you unlike,
  the existing notifications about the like are revoked.
* The notifications appear as an alert number in the nav bar and are read
  on the User Dashboard. Click to mark a notification as "read" or click
  the "mark all as read" button.

Update DeleteUser to scrub likes, notifications, threads, and comments.
