Increase match percent to 70% to improve demo (this logic was changed on day of Hackathon) and clean up match logic (was done today, several days after Hackathon).
Change # of turns per game to improve demo (this logic was changed on day of Hackathon).
Add watch app icons modified to be correct size.
Remove unneeded UI elements left over from hurry to finish Hackathon implementation in allotted time.
Add (temporary?) Game Over label after game ends.

Primarily so that button is no longer visible, and so tapping it after game ends does not lead to a crash.

In full game, score will be determined afterwards by comparing tap times of all players.
