* On a user gallery page: if the current user can not see their default
profile pic (friends-only or private), include a notice and link to
the FAQ about this.
* Add a new placeholder avatar for profile pics that are set to
"Inner circle only" when viewed by members outside the circle.
* 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
