  Modified files:              
    /loncom/interface	coursecatalog.pm 
  Log:
  - 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.
