New feature! Sentence stats

#1

Stats for typos, hints, pauses, and time elapsed for each sentence are now tracked :tada: The stats are saved when a sentence is completed, and you can see the stats for each time a given sentence has been completed from here on out (alas, we don’t have these stats for sentences completed up to now).

Longer term we’re aiming to get some cool graphs/visuals added so you can more easily see your progress.

Please let us know of course if you have any feedback or there’s anything you think might make it more useful!
