move graded by info to top of window
when grading with a team it quite often happens that you request a new ungraded student at the same time. The system shows that the first grader has graded it, but it still shows it as as ungraded to the next grader. By moving the "graded by" info to the top of the page a grader doesn't have to scroll down to check if someone is already grading this students response.
