Some small issues with Excel export remain
- There seems to be no page numbering.
- Are the background colors of the rows alternating from theme color to white and vice versa? (I don't have enough test data.)
- Are the players' names sorted by answer times?
- Percentage values and answer times should be rounded. No pseudo exactness please.
- It would be very nice to have some PR: Insert texts into header and footer at least for the first page, e.g. "Quiz and ranking data generated from a live quiz session with arsnova.click" (header) and "arsnova.click is open source software, see arsnova.io and https://github.com/thm-projects/arsnova.click" (footer)
- State the quiz file name for later searching: "Exportiert am ... um ... Uhr in die Datei »Export-Demo Quiz 256-7_3_2017-15_26« "
