6.x CourseList.php	CourseList::sort_smallest_hours_first()

This will sort so that courses with the smallest hours (first trying hours_awarded, then min_hours) are at the top of the list. If the list contains more than one course with a set of hours (like there are 30 courses all worth 3 hours) then it orders those as most-recently-taken first.

  // We will transfer over the reference.
