Work in progress!!
Work in progress!!

I doesn't work at all but near every question type has been checked and
changed if needed. Tomorrow I'll start with the quiz->attempts... part

Anyway I've some IMPORTANT doubts about how this questions are currently
implemented:

- NUMERICAL: Can the answer field have more than one answer?
- MULTIANSWER: What are the differences. Why, in the upgrade process,
     all of them are deleted and recreated? Why some fields have been
     deleted? Why the questiontext for this type is set to '' in the
     upgrade processs
- CALCULATED: Why the quiz_question_datasets table is now simply "s" in
     the restore process? A typo, I hope.

I've written this here to avoid forgetting it and, if someone in the
quiz's team can answer me...

Now, just zzzZZZzzzZZZ. Ciao :-)
