Improve submission navigation in mobile SpeedGrader Upgrades

[paulamiranda]

In the Teacher app, specifically, the only way to navigate student submissions is by swiping the screen left or right, which would take instructors/graders to the next, ungraded submission and the last graded submission, respectively.

To make navigating submissions easier, especially for instructors/graders of large enrollment courses, we ask for the following functionality, which would bring parity between the mobile and desktop SpeedGrader experience:

• A list of student submissions where instructors/graders can select a submission

• Different sort settings

• Written instructions or a more intuitive user interface for how to navigate between submissions. currently, it's not clear that a user will have to swipe the screen and the arrow buttons are somewhat misleading, because they expand/collapse SpeedGrader panels rather than move through the submissions)
