course/scales.php reallllllllly slow

The scales.php script checks all the site wide custom scales against every course in the database to check if its used. This really slows down the page.

This checking is not necessary unless the person accessing the scales.php page is the administrator, since it is only the administrator who can edit site wide scales.

The version i am using is Moodle 1.4 development (2004070800)
