Important update: Russian quizzes

Since around 40% of my quizzes are in Russian, I’ve adjusted them so that Ё/ё is accepted the same as Е/е, just as in real usage. For example, you can write мёд (honey) as either мёд or мед.

There might still be a few quizzes I haven’t caught yet, so if you spot any, let me know and I’ll fix them.
