Participation buttons on the intermediate page for the students

[Peterrahr]

The participation buttons on the student intermediate page can be confusing to understand. Right now is the list ordered in a way such as the newest participation is called nr 1 and ordered in newest first. No visual information is provided on the page such as date, score for the quiz, time used etc.
A way to improve the list is:

• Take inspiration from the standard Moodle Quiz. They represent all information in a table
• The information needs to be stored in the quiz-student relation table

We believe it is a good first issue since it provides a better overview for the students. Improvement of #121 and #122
