* Add "Like" buttons to comments and forum posts.
* Make "private" profiles more private (logged-in users see only their profile
pic, display name, and can friend request or message, if they are not approved
friends of the private user)
* Add "logged-out view" visibility setting to profiles: to share a link to your
page on other sites. Opt-in setting - default is login required to view your
public profile page.
* CSRF cookie fix.
* Updated FAQ & Privacy pages.
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.
