CVS tags:
HEAD
- New subroutine: &additional_filters() generates checkboxes to apply in course
search (self-enroll only, DC only: display hidden & show all details).
- "Go" buttons for updating domain used for coursecatalog and category to search
replaced with "Change"
- "Display course" button displayed for both searches for official courses and
for manually assigned categories.
- Some javascript changes so changeSort() and setCourseId() are available for
both types of search. copy_filters() function no longer needed.
