Renamed test.php ==> tester.php, noop.php ==> test.php. Updated the self-test in admin.yaml to point to test.php. Moved running the tests to the overview page.
Removed the noop.php file
Added a new method called updateTests that will update the elements in the overview area so that the tests don't get run again. Uses the tests in the sidebar to determine if the test has already been run
