'self_nominate', and 'schedule_judges'.
- self_nominate defaults to 'yes' for all new and existing awards. If turned
off, the award will not appear in the student self-nomination pages.
- schedule_judges specifies whether an award should have judges or not, we have
some special awards that students can nominate for but do not require judges
to find the winner. Similarly we have some awards students cannot nominate
for but do require judges to determine a winner. This allows both cases to
be handled.
