MDL-35074: grader report - Ease limit on number of students per page

The limit imposed by max_input_vars "applies only to each nesting level of
a multi-dimensional input array"
(http://www.php.net/manual/en/info.configuration.php#ini.max-input-vars).

Turning the grader report fields into arrays (they were all top-level form
fields, i.e. elements of the top-level array) makes the number of students
become the only limiting factor, thereby allowing us to relax the limit on
number of students per page greatly (to 1 less than max_input_vars, for
safety).
