Title: Grader display updates

This should close issue #187.

Instructors can now toggle whether or not a Student's status is dropped.

The Assignment show page Results section is now segregated by Registered, Auditing, and Dropped to make it easier for the graders to figure out what is happing with a particular student. Percent correct summaries are computed per group. Researchers still see only consented Student information.
