Subject: [PATCH] feat(tazjin/russian): Echo Russian words when Emacs is idle

This should keep up passive exposure to words, but needs a subsequent
function for filtering out things that are definitely known.

Since I'm keeping the frequent word list mostly intact the majority of
words are very basic, but it's those last 15-20% I'm interested
in (not completely imported yet).
