Add options to show/hide the history and the correct answer

[PhilippImhof]

This PR adds two options that allow the teacher to decide whether or not to include the history of saved answers and whether or not to include the correct answer.

I took the liberty to do some major changes to archive_options.php, because using another parent class made much of the existing code redundant.

The PR includes a behat test for the two options.

Thanks so much @PhilippImhof for this improvement, which I'm going to merge.
I've looked at the used strings and propose a slight amendment which I will edit in:

☐ Include response history table
☐ Include correct answer banner

Because I was seeing the green ✅ ticks in the questions and thought "Hey, this distinguishes the correct answers, too, doesn't it?".

I noticed an additional thing, which is that if there is no attempt at all, the report just shows those
☐ Include response history table
☐ Include correct answer banner
options and the "Show report" button again. You might think the button didn't work. A notice with the string "There are no attempts to show" (quiz|noattemptstoshow) could come in handy.
I will create an issue.

Best,
Luca
