Work toward #849.

Also removes the condition causing the error in #846 but does not address the underlying problem with #846 in that a validation error on Add put the form in a bad state.
#849 - Row level security stub interface; WIP
Make the fetch criteria for row-level security more intentional for #849
Add update hooks for row-level security as apart of #849

#849 - Remove the row-level security checks on an add since it doesn't make sense, add hooks for delete
Allow AdminPermissions to be managed in the admin #849.

This requires the latest admin_menu, admin_roles, and admin_permissions SQL files to be run  (or at least the changes visible in the commits below).

In addition, to allow the Admin user to Maintain or View the Permissions menu item, you will need to manually assign them that permission.    It was left off by default since this is intended for Advanced usage only.
