HEAD
- Change link to "Enroll in course" to javascript:ToSelfenroll() which submits linklaunch form.
- Filters used in coursecatalog display passed to selfenroll to allow breadcrumbs there.
- syllabuslaunch form renamed linklaunch form (no longer used for just syllabus).
- &syllabus_javascript() renamed courselink_javascript() - broader use.
- 'courseid' added as another element to exclude from echo of form input to avoid duplicate
when coming from breadcrumb trail link in self-enroll.
