* Add "Site Gallery" page showing all public+gallery member photos.
* Add "Certification Required" decorator for gallery and other main pages.
* Add the Certification Photo workflow:
* Users have a checklist on their dashboard to upload a profile pic
and post a certification selfie (two requirements)
* Admins notified by email when a new certification pic comes in.
* Admin can reject (w/ comment) or approve the pic.
* Users can re-upload or delete their pic at the cost of losing
certification status if they make any such changes.
* Users are emailed when their photo is either approved or rejected.
* User Preferences: can now save the explicit pref to your account.
* Explicit photos on user pages and site gallery are hidden if the
current user hasn't opted-in (user can always see their own explicit
photos regardless of the setting)
* If a user is viewing a member gallery and explicit pics are hidden, a
count of the number of explicit pics is shown to inform the user that
more DO exist, they just don't see them. The site gallery does not do
this and simply hides explicit photos.
