Update Typo Storage

The Typo Action to report a typo is in need of some overhaul:

• It's one of the few remaining relational DB entries, and would work quite well as Document DB entries instead. Move Typo data to be stored as a document in the document DB, and delete the old TypoRecord.
• There seems to be no way for admins/builders to review the typo entries. (Would be great to be able to list ones which were reported from rooms in the current area, so a builder can work to repair typos specific to their own area, etc.)
• Also should be able to mark them as complete, or even fully delete the entries (by an admin only). Marking complete could adjust a flag on the Typo object and re-save it to the document DB.

First point is done. Still need to add the commands for review and marking them complete.
