* For admins, make it a specific opt-in filter for the Site Gallery to
show all pictures regardless of friendship or grant (for moderation
purposes). On this view, Like and Comment buttons are taken away.
Non-admins are not shown the option and the back-end ignores the
parameter for them.
* Fix user avatars on compose and admin actions page.
* Users who set their Profile Picture to "friends only" or "private" can have
their avatar be private all over the website to users who are not their
friends or not granted access.
* Users who are not your friends see a yellow placeholder avatar, and users
not granted access to a private Profile Pic sees a purple avatar.
* Admin users see these same placeholder avatars most places too (on search,
forums, comments, etc.) if the user did not friend or grant the admin. But
admins ALWAYS see it on their Profile Page directly, for ability to moderate.
* Fix marking Notifications as read: clicking the link in an unread notification
now will wait on the ajax request to finish before allowing the redirect.
* Update the FAQ
