Course Requests.
- Pass additional arg to loncommon::construct_course() - category to identify whether requested course is official, unofficial or community.
- Pass two additional args to lonnet::createcourse() - context (e.g., requestcourses) and category
- used when checking that requestor has rights to request a course (check via &usertools_access())
- Additional role assgnment rights check in &lonnet::assignrole().
Support case where a requestor is creating a course, and as course owner needs CC role
These rights only applies where context is "requestcourses", and user is adding his/her own cc role, and is identified as course owner.
- Defalt to using $en{'user.name'} and $env{'user.domain'} if not supplied in the args to &store_userdata().
