In various places, when showing several attempts, we try to hilight the most significant one (the one that gave the final grade if the quiz is set to first/last/best attempt). That was not working because the table zebra stripes were a more specific rule. Also, the colour was inconsistent, not nice, and not very bootstrapy, so I changed it.
