Bug fixes

Purpose

Fixes a couple bugs.

1. Makes the arrow keys work when the checkbox is in focus.
2. (not a bug) Removes unused code.
3. Upgrades ffish, which fixes Support 3check pasting of other FEN variants #185

Pre-merge TODOs and Checks

• PGN file loads correctly
• Navigating through the move history works
• Starting the engine shows moves (test for both sides)
• Selecting a different variant loads a new board with the variant and you can make moves on the board
• In Crazyhouse the pocket pieces are shown and you can drop pieces

It looks like it didn't pass the check because I've always been having to use --legacy-peer-deps in order to get it to build. I'm probably just doing something stupid, but using npm and dealing with dependencies is very new to me.

Thanks for the updates. I see, should we remove package-lock.json in this case to fix the lint issue?

[ksthicke]

Whatever you did with package-lock.json seems to have worked -- thanks!

[QueensGambit]

Great, that it works now.
I set ffish": "^0.7.6 and run npm install locally.
Next, I uploaded the resulting package-lock.json file.
