MDL-65915 quiz regrading: better progress information
This makes it easier to diagnose problems if the regrade fails in the
middle.
Along the way, I added one un-declared field to the class, and
converted some SQL-construction code to $DB->get_in_or_equal().
I also added the ability to set attributes on the label in
html_writer::checkbox.
