Bug 1470 - reimplement single student view in chart.
lonstatistics.pm:
  Changed handling of $curr_student, $prev_student, and $next_student.  Now
  assumed to be undef when they are not appropriate.
  Renamed 'StudentAssessmentStudent' form parameter to 'SelectedStudent'.
lonstudentassessment.pm:
  Added package variable $single_student_mode to flag the single student mode.
  Added hidden form parameter 'sort', to maintain sort key.
  Added &next_and_previous_buttons to present the user with 3 buttons:
	"previous student", "all students", and "next student"
  Added &SingleStudentTotal to output an html table with some statistics about
        the students performance.
  Modified &html_finish to call &SingleStudentTotal instead of
	&StudentAverageTotal if in $single_student_mode
