Never allow duplicates among Grade Center Categories

    When copying courses, the list of Grade Center Categories can grow through duplication. The Categories list currently does not restrict the names to be unique, resulting in instructors' confusion and frustration when they see multiple entries on a Category-selection menu. The programming that controls the list of Categories needs to be fixed to restrict the entries to have unique names.
