- DC can display either requests queued pending validation of instructor,
or queued pending approval.
- Validation can be attempted for pending requests
- any validated will be created automatically.
- unvalidated will be displayed with the option to approve/reject
- &process_official_reqs() moved from Autocreate.pl to facilitate re-use.
- New routine: &build_queue_display() created from code previously in
&display_queued_requests() to facilitate re-use.
