Course Requests
- lonnet.pm
- generation of unique coursenum move to own routine: &generate_coursenum()
- prefacing of coursenum with number then letter added to second attempt
to generate an ID (to duplicate change in first attempt in rev 1.674).
- additional optional argument to &createcourse() - can use a previously
generated, but unused, coursenum (will be hashkey in a queued course request).
- loncommon.pm
- additional optional argument to &construct_course() - $cnum, previously
generated, but unused, coursenum.
- check_clone() - unrestricted cloning in course's in role's domain now
requires creator has ccc privilege in role's domain.
- batchcreatecourse.pm
- &build_course() - update documentation, and new optional arg
previously generated, but unused, coursenum
