New quiz option - "Each attempt builds on the last"
This makes it possible for students to take a tedious quiz, save it half-way and have it graded. The student can then, at a later point, get back to the quiz and have the previous answers already filled in and graded. The student can then continue with the remaining questions as well as redo all the answers that got wrong at the previous attempt.
It seems to work fine with one little twisted exception:
Say that the student attempts the quiz first and that the teacher thereafter edits the quiz and removes or adds a few questions. This will work out fine for as long as the teacher do not get the idea of adding a question with question type RANDOM. The quiz will be fully functional again after removing that RANDOM question or resetting the option 'Each attempt builds on the last" to NO.
Not a very serious problem but it takes someone with greater insight in question type RANDOM to resolve it.

Resolving bug #576.
This solution shows the message "Recently added question!" and the question text for each question that has been added since the reviewed attempt.
The advantage with the chosen solution is that it will work fine for the (soon to come) "Each attempt builds on the last" quiz option.
As I don't have the karma needed for updating in lang/en/, the message does not yet look quite as I described it above.

Debugged question types NUMERICAL and MULTIANSWER (known as embedded answers) as these did not do things right whenever a student had not given any response (was treated as zero etc).
For numerical there was also a need to allow typical shortanswer responses whenever there could be answers like n/a, inf, -inf, nan etc.
Further more about numerical, there can be more than one answer alternative defined (just like for shortanswer). This is not supported by numerical.html but everywhere else. MULTIANSWER included, it is up to any taker to update numerical.html. This is more than likely to lead to overlappings between numerical ranges if more than one is defined. Think of the case where the highest grade answer ranges between 0 and 2 and the half grade answer ranges between 2 and 4. How should we grade 2? We should pick the highest grade!

Now, when a category exists, if we are restoring to a different course,
set utomatically the publish field to 1.
If a question exists in DB (by category, questiontext and qtype) it isn't
duplicated.
This produce some problems restoring answes, but avoid duplicates.

Teacher restoring and admin restoring finished.
Allow restore into new course (only admins),
restore into existing course deleting old and
restore into existing course adding to old
Teachers are limited to "current course" while admins ca
select any course. :-)

Now "backupdir" string is hardcoded in backup process.
Backup of logs in chunks is included, but the limit
clause doesn't seem to work. I'll test it later.
Refactoring only, no new features -
Modified methods are quiz_get_answers and quiz_grade_attempt_results.
For quiz_grade_attempt_results, the switch statement has been separated out into method quiz_grade_attempt_question_result.
Fixed important bug when recovering assignments or forums
with files and the moddata/courseid didn't exist.
Now force the creation of the courseid dir from the
restorelib in each module.
