- 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.
