I support the new board and piece DOM update

I've noticed the new DOM had variables in root like --theme-piece-set-wp which makes it a lot easier to style pieces and boards using just CSS. I already updated my own code when it broke down, but it's still going between the old and new versions, which is annoying.

Not really API related but there is new themes code that is live to some site members.

Yeah, I got the update like two days ago and re-wrote my code. It's actually a good update, but for some reason, it reverted back to the old version today. It would be nice to just have a toggle for always keep on latest update (even if experimental).

Yes, success.
