More screenshots in the Plugins directory

It would be nice to have a bit more screenshots in the plugins directory at https://moodle.org/plugins/quiz_answersheets

The screenshots could

• Highlight the tool specific features in the report (the last four columns in the table basically)
• Illustrate how the printed sheets look like etc.

As usual David, you are right. We just need to find time between checking all our plugins for 3.9-compat, and preparing for Global Moot, etc. Now that you have created this issue, hopefully we won't forget. Thank you.
