Noah de9ba94dd9 Private Photo Sharing
* Add ability to unlock your private photos for others.
    * Link to unlock is on another user's Photos page.
    * You can also access your "Manage Private Photos" page in the User Menu
      or Dashboard and add a user by username.
    * See who you have granted access, and see users who have granted you
      access to their private photos.
* Private photos of users who unlocked them for you may appear on the Site
  Gallery if the photo allows.
* Add new filters to the Site Gallery: you can choose to filter by Explicit,
  limit to a specific Visibility, and order by Newest or Oldest. Non-explicit
  users do not get a filter to see explicit content - they must opt-in in
  their settings.
* Bugfix: Site Gallery was not correctly filtering Explicit photos away from
  users who did not opt-in for explicit!
