Add spelling game

[ericadamski]

It would be awesome to have more games that can teach things like spelling! Something like, you press a key and a emoji is display and the word is said but at the bottom of the screen under the emoji instead of the letter we should the word partially spelled. The the user has to fill in the missing letters.

There could be multiple levels of this, the first level is only a few missing letters and the place holders have the correct letters in them.

Another level could be no letters but all placeholders show the correct letters.

Or the hardest level would be just the correct number of blank spaces

Really terrible text example:

🍎

A ? p l e

---

This will need a new menu screen to pick different games and a new input and validation flow. (see #56 )
