* Add 'admin labels' to photos so an admin can classify a photo as:
* Not Explicit: e.g. it was flagged by the community but does not
actually need to be explicit. This option will hide the prompt to
report the explicit photo again.
* Force Explicit: if a user is fighting an explicit flag and keeps
removing it from their photo, the photo can be force marked
explicit.
* Admin labels appear on the Permalink page and in the edit photo
settings when viewed as a photo moderator admin.
