Deadline for late submissions
Late submissions currently allows students to make a single, one-time upload after the hard-deadline.
This functionality should be refactored to include a personal new hard-deadline for the student. Until the hard deadline the student should be allowed to make any number of uploads.
The Late Submission can be most likely removed from the codebase as a result.
Version controlled tasks should also handle this new feature accordingly.
