- Bug 6979
- Shortcut to student's view of problem etc. from 'View As' item in Functions
menu above problem.
- Part of code in &submission() subroutine in grades.pm moved to separate
subroutine -- &show_last_submission() which can be called by &view_as_user(),
which in turn is called from lonhomework.pm
