feature: show typos on the virtual keyboard after a lesson

[aradzie]

When a lesson is completed, we show a heatmap overlay on the virtual keyboard. In addition to this, explore the possibility to show typing errors in the form of an arrow from the intended key to the actually typed key.

I believe this is a substantial feature which requires quite a few changes. To begin with the information about those errors is not recorded anywhere, and the text input component must be updated to record incorrect key presses. Then the virtual keyboard component must be updated as well with a new layer do display errors.

Sorry, no. I want to do it myself. Try something simpler first.
