If a quiz activity has negative grading enabled for incorrect answers,
students can achieve overall negative grades in this quiz. If at least
one student achieves a negative grade, the chart at the bottom of the
quiz 'Results' tab will fail to display. This patch add a search for
negative results, removes them from the band below 0 and adds them to
the 0 band. This will make the chart render correctly again.

Removed whitespace at end of lines
Júlia, from the PX team, has suggested a few improvements to make it easier to
understand the Restore main page:
- Displaying a notification instead of the empty table when there are no files
in an area.
- Improve the copy, removing the help buttons and moving this information to the
main page.
- Replacing "Import a backup file" with "Upload a backup file".
- Adding some space between the different areas.
- Displaying a different text in the different "Manage backup files" buttons.
It is correct that the database default should be 0, to match
other similar columns, but when sites are upgraded, we need
to set the settings for all existing quizzes to match the previous
behaviour.
The correct way to get an ad-hoc task to run as the main admin account
is to leave userid as null.
Setting it causes fatal errors if the main admin account is set to
auth: nologin.
Moves the data-filtercondition property to an element that always
exists regardless of whether the selected category from the filter
has questions or not. This will effectively solve the exception
that is being thrown due to the non-existing element and also
enable creation of random questions in a category that does not
have any questions yet. Also, the data-filtercondition attribute
is no longer used when creating a random question in a new category
as this value is not relevant in this case. Instead, a default
filter condition is generated in the webservice for the random
question based on the newly created category.
Previously, quiz statistics processing happened on a scheduled task.
This task looked for all quizzes with completed attempts, then
determined if those quizzes had a statistics calculation that's newer
than the most recent attempt, then ran the statistics calculation if
needed. It was hard coded to stop processing after 1 hour.
The queries involved in determining which quizzes needed processing
weren't terribly efficient, and combined with the 1 hour limit this made
the statistics unusable on large sites, where they are the most useful.
This converts the scheduled task to an ad-hoc task, and uses an event
observer for mod_quiz\event\attempt_submitted to queue a task when
it is needed. This removes the need for a query to work out what needs
processing, and allows the task processing to be scaled up as needed.
This modifies the question_data fragment used by the filter code to make its
parameters closer to the URL parameters of the question/edit.php page. This
Allows us to progressively enhance the add, remove and reset actions on the
question bank page, using this same fragment to reload the question table after
each change. This re-uses the same actions.js module used for enhancing these
actions on the qbank_columnsortorder admin screen.
