Major Update 6/6 -- Scan Management

[Secret Squirrel]

With this final major update, the core submission and moderation system is finished. Undoubtedly there are still some changes, tweaks, and fixes to come, but the major work is finished. With these most recent changes:

• Scan properties can now be edited using the 'Manage Scans' choice in the Edit menu.
• A credit link has been added to the single scan display.
• Edits by staff and trusted editors bypass the moderation queue.
• Staff can accept and reject edits using the moderation queue control panel.
• Staff can delete scans from the Manage Scans form.

Now that the major work is finished, our main task will be polishing things up in preparation for beta.
