- PEP8 for every method I touched.
- Removed the clean method of SubmissionReviewForm as it didn't do anything. The max_points will always be None so the if-statement will never evaluate to true. The points < 0 check is done by the IntegerField anyway.
- Added help_text to the SubmissionReviewForm.points
- In the submission_assessment view, the set points is called with the new no_penalties argument so points of the manual assessment will be set to the Submission exactly as given.
- Submission.set_points now supports no_penalties arguments. If no_penalties=True is given, the set_points will not apply late_submission_penalty to the given points.
