* 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!
