-Added groundwork for open/closed registration. This variable needs to be saved in the back end somehow, so the functionality is currently not working.
-Deactivate/Reactivate user functions now call a user update. I cannot verify if these functions work until the userByID problem is fixed.
-Added option in admin dropdown so admin may see the current value of registration and toggle it.
