This is a relatively small update, but it has a wide impact.
- Scans can be uploaded by selecting 'Add Scan' in the Edit menu.
- Scans uploaded by staff and trusted editors bypass the moderation queue.
- Staff can accept and reject scans uploaded by anyone else.
All that remains from the core behavior is editing scan properties (which will include delete.) I'll work on this next week, as I'll be out of town this weekend.
