Fixes bug #73 and altering of all fingerings table/search for admin and regular users.
Regular user all fingerings table/search will not display unapproved fingerings.
Admins will be able to see all fingerings (whether approved or not), and these are marked with a red border in the all fingerings table.
If an admin edits a fingering or creates a fingering, then the fingering does not need approval/re-approval.
If a regular user edits one of their fingerings, the fingering now needs to be re-approved by an admin.
