HEAD
- Breadcrumbs added to facilitate retreat to earlier pages during account creation process.
- &catreturn_js() added to provide javascript functions used in breadcrumb trail to jump back to
course catalog or first self-enrollment screen, when account creation occuring in context of self-rnrollment
- &print_footer() added to provide backupcrumbs form where coursecatalog search terms are stored so breadcrumb links can jump back to entry point from course catalog in self-enroll context.
- &selfenroll_crumbs() added to provide additional breadcrumbs in selfe-ennroll context.
- &login_failure_msg() added to put messages displayed when authentication fails in one place, with a link back to try again.
- form element cid renamed courseid (and $cid renamed $courseid) to avoid confusing this with the cid form element used for entering a studentID in loncreateuser:personal_data_display().
