Added the ability to delete or clear notifications.
* A "Clear all" button deletes them all (with confirmation)
* A "Remove" button on individual notifications (one confirmation per
page load, so you can remove several without too much tedium)
Fix some things regarding private photo notifications:
* When notifying your existing grants about a new upload, only users who
opt-in for Explicit are notified about Explicit private pictures.
* When revoking private grants, clean up the "has uploaded a new private
photo" notifications for all of your pics from their notification
feeds.
Add a permission system for admin users so you can lock down specific admins to
a narrower set of features instead of them all having omnipotent powers.
* New page: Admin Dashboard -> Admin Permissions Management
* Permissions are handled in the form of 'scopes' relevant to each feature or
action on the site. Scopes are assigned to Groups, and in turn, admin user
accounts are placed in those Groups.
* The Superusers group (scope '*') has wildcard permission to all scopes. The
permissions dashboard has a create-once action to initialize the Superusers
for the first admin who clicks on it, and places that admin in the group.
The following are the exhaustive list of permission changes on the site:
* Moderator scopes:
* Chat room (enter the room with Operator permission)
* Forums (can edit or delete user posts on the forum)
* Photo Gallery (can see all private/friends-only photos on the site
gallery or user profile pages)
* Certification photos (with nuanced sub-action permissions)
* Approve: has access to the Pending tab to act on incoming pictures
* List: can paginate thru past approved/rejected photos
* View: can bring up specific user cert photo from their profile
* The minimum requirement is Approve or else no cert photo page
will load for your admin user.
* User Actions (each action individually scoped)
* Impersonate
* Ban
* Delete
* Promote to admin
* Inner circle whitelist: no longer are admins automatically part of the
inner circle unless they have a specialized scope attached.
The AdminRequired decorator may also apply scopes on an entire admin route.
The following routes have scopes to limit them:
* Forum Admin (manage forums and their settings)
* Remove from inner circle
* Refactor the Settings page into a tabbed UI to reduce confusion with
all the different forms and save buttons
* Add a DM Privacy setting to your page
* Update the About page
