Added view for editing GradingRecords.
This view shows a list of GradingRecords if the id param is not present in the GET data.
Also renamed grading_record to view_records and fixed the redirect for that page
to also point to the GradingRecord edit page.
"""
Create a superuser from the command line. Deprecated; use manage.py
createsuperuser instead.
