The sequence of questions that made up a quiz used to be stored as a
comma-separated list in quiz.questions. Now the same information is
stored in the rows in the quiz_slots table. This is not just 'better' in
a database design sense, but it allows for the future changes we will
need as we enhance the quiz in the MDL-40987 epic.
Having changed the database structure, all the rest of the code needs to
be changed to account for it, and that is done here.
Note that there are not many unit tests for the changed bit. That is
because as part of MDL-40987 we will be changing the code further, and
we will add unit tests then.
It is only necessary when there are (non-preview) attempts. However,
after making this change we have to ensure users cannot start attempts
when ->grade > 0 and ->sumgrades = 0.
Display ->grade on the order and paging tab of edit.php, so it is clear
what is going on when you are using that tab.
Finally, improve the error message a student gets if they try to start a
quiz with no questions.
Some help icons dropped without replacement as suggested by Helen, the
Help Writer. Some strings moved to core_question.
