- New awards for surveys:
ANONYMOUS ANONYMOUS_CREDIT SUBMITTED_CREDIT
- given for question types: anonsurvey, anonsurvey_cred, survey_cred.
- anonsurvey -- course personnel can not view both identity of submitter
and submission details.
- anonsurveycred -- same anonymity, but submitter receives 'awarded' for
submission
- surveycred - submitter receives 'awarded' for submission to survey.
