Fixed a bug that caused everything to break.

Now looking for admins of the project, rather than admins of the key.
Access levels work

'Make Private' and 'Make Public' buttons now work.
User Access Levels

Users can be given admin and access levels. Really simple stuff.
Versions

Versions of pages are now accessible. New versions can be added, and
versions can be rolled back. 'Update' keeps comments, 'Replace' deletes
them.
Creator tracking

Creator of each version is now tracked, for future purposes.
Readme

Added the Readme, explaining all current commands.
