[Speedgrader] Improve speed and effectiveness with a menu

[AdamKundurakis]

Problem statement:

After have been working in speedgrader for 4 years, I start to believe it is actually a bit slow because there are so many clicks to navigate.

Proposed solution:

I would suggest replace the drop-down menu with a permanent menu with separate buttons for passed/not passed/excused. See picture. This is to easier correct stuff, get a better overview and quicker correct when you have a lot of easy assignments etc.
