Course requests.
- Moving and modifying some routines used for displaying queues (oringinally created for approval/rejection of self-enroll requests to also support approval/rejection of course creation requests.
- &display_selfenroll_queue() moved from loncreateuser.pm to loncoursequeueadmin.pm
(and renamed &display_queued_requests() ).
- &update_selfenroll_queue() moved from loncreateuser.pm to loncoursequeueadmin.pm
(and renamed &update_request_queue() ).
- &get_student_counts() moved from loncreateuser.pm to loncoursequeueadmin.pm
- &send_notification() moved from selfenroll.pm to loncoursequeueadmin.pm
(and renamed &send_selfserver_notification() ).
