If you dragged a question to the top of the quiz, it could
disappear. Several other cases of dragging questions to the
same place in sequence, but to a different page/section were
also failing, and have been fixed.
Some search areas have been introduced as part of the initial search API
and search engine API implementation.

The sections are created on the edit quiz page, and then appear in the
navigation panel when the quiz is being attempted to help students find
their way around.
The 'Shuffle questions' setting has been moved from being per-quiz
to being a per-section.
This commit is actually the joint work of Mahmoud Kassaei and Tim Hunt
from The Open University. We could only use one persons name for the
commit and this time Mahmoud gets the credit/blame.
There are several improvements over what we had before:
1. We track all the questions seen in the the student's previous
quiz attempts, so that when they start a new quiz attempt, they get
questions they have not seen before if possible.
2. When there are no more unseen questions, we start repeating, but
always taking from the questions with the fewest attempts so far.
3. A similar logic is applied with variants within one question.
There is lots of credit to go around here. Oleg Sychev's students Alex
Shkarupa, Sergei Bastrykin and Darya Beda all worked on this over
several years, helping to clarify the problem and shape the best
solution. In the end, their various attempts were rewritten into this
final patch by me.
Further improvements to this code, including resolving edge cases:
* The new feature can only be used when it is possible for the
previous question in the quiz to be complete.
* Also, this new feature cannot be used in combination with shuffle
questions, because that make no sense; nor in combination with
sequential navigation, because to make that work properly would be a lot
of effort. If someone needs that to work later, it should be possible
for them to implement it.
* There were changes in the edit renderer API, to try to make things
more consistent, and to make it less likely we will need to change
things again in the future. See mod/quiz/upgrade.txt.
* As part of this change, the styling of the Edit quiz page was tweaked
to make slighly more efficient use of the horizontal space, and to be
more symmetrical.
The unit tests were initialising the structure class in a different way
from real use. That was clearly silly, so I got rid of create_for,
leaving just the real create_for_quiz.
