Form for each student

[danielneis]

Hello,

This adds an option on mod_form to generate one answer form per student, pre filling their idnumber, firstname and lastname,
The generate file is a unique PDF for all students.
I've not indented the main part of the code intentionally to easy the review process, but once you approve it I'll make that change.

Best,
Daniel

Hi Daniel,

thank you for your pull request.

We are generally very interested in your changes. There are just some caveats whe have to solve before fixing this issue:

1. This feature would be for the next version (offlinequiz 4.4) first. I changed the branch to master for this. It would be nice if you could rebase your changes to that branch too.
2. We would like to have an admin setting so the admins can disable this feature for new offline quizzes.
3. One important question is the allocation: Which user gets which group. There is no point in printing 6 pdfs for each user, if there are 6 different groups. Maybe you could use the participants lists for that? It's definitely something to be discussed.
4. If the setting is enabled there should also be the empty one be included. Teachers should be able to print this one out for emergencies.

That's the immediate feedback. I will come back later with some more.
