Add exam time page link to course page

[Enturk]

Currently, the accommodations page to extend the time available for exams is not linked anywhere else. So, to reach the accommodations page:

• https://blockpy.cis.udel.edu/courses/manage_time/?course_id=4721

One cannot click on anything on the course page to get there:

• https://blockpy.cis.udel.edu/courses/4721

Because the only people that have to do this know how to get there, this is a low priority issue.

Actually, it IS linked now. If you scroll further down, I believe it's named "Manage Time" or something like that.

That said, Katie identified a bug yesterday with how it saves, which affected the 181 DSS exams. Basically, assignment groups weren't being linked correctly to submissions (just assignments). A different issue was also present; I missed one part of the second exam for a student, and it meant that their exam closed prematurely when they got to that question.

All this to say, that interface must be rewritten to handle assignment groups instead of assignments. It's simply not sufficiently usable as it is.
