Adds the option to change the WK extra study to audio => meaning questions.

Adds a switch "Audio Quiz" to the extra study section on the dashboard. If it is enabled, all extra study sessions will only consist of vocabulary items with audio => meaning questions. Whether it works depends on the script manager's injection speed: If the page fetches the queue before the script manager injects this script, the queue might also contain kanji and radicals which increases the difficulty (because no audio plays for those).
