Tweak voting view & Debug attendee voting
Via Debug.addMembers(x) added quiz attendees will now participate on the quiz.
Reworks the voting view. The answer buttons will now scale responsive depending on the screen's width and height and the number of answer options. For devices > 768px (tablet size) it should not be necessary to scroll anymore. Devices <= 768px will order the buttons in two rows.
If there are too much buttons it will be necessary to scroll for them.
