Added the ability to delete or clear notifications.
* A "Clear all" button deletes them all (with confirmation)
* A "Remove" button on individual notifications (one confirmation per
page load, so you can remove several without too much tedium)
Fix some things regarding private photo notifications:
* When notifying your existing grants about a new upload, only users who
opt-in for Explicit are notified about Explicit private pictures.
* When revoking private grants, clean up the "has uploaded a new private
photo" notifications for all of your pics from their notification
feeds.
* Add support to upload a picture to forum posts and replies, in forums that
have the PermitPhotos setting enabled.
* New DB table: CommentPhoto holds the association between a photo and a
forum ID. Photos can be uploaded at preview time (before a CommentID is
available) and get associated to the CommentID on save.
* Cron endpoint /v1/comment-photos/remove-orphaned can clean up orphaned
photos without a CommentID older than 24 hours.
* Add "Photo Boards" as a default forum category for new boards.
* 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.
