Update: Piece icons

Just swapped out algebraic notation letters for piece icons, so Chessguessr should be easier to play for people not used to algebraic notation. Go check it out at chessguessr.com :)

After receiving feedback from beginners, I introduced the icon-based notation to make it more accessible for them. However, I understand that experienced players prefer the original notation. I'm working on an update to allow users to select their preferred style. Until that's ready, original notation will be used.

eee
