[Studio] Studio Quizzes: Watch Videos Again Without Retaking Quiz

[ashlib]

It would be great if Studio had an option in addition to "retake" a quiz to simply "watch the video again." This would allow students who've already passed the quiz to watch the video multiple times without having to take the quiz every time. This could also potentially allow students to watch the video again for Studio assignments with lock dates. The video could remain available. Right now, the only option is to create the video quiz assignment and then add an additional link to the video separately.
