Add some way to change the previewed piece in Lishogi's piece set menu.

Not sure myself how a UI for this would be made, but being able to change the previewed piece from a Gold General in the Piece set menu to another piece would help players find their preferred set better without going through everything to find the one they want.

Not all pieces have to be in there, a handful such as a Gold for obvious reasons, A Silver to distinguish coloured piece sets, a Dragon Horse to distinguish red and black promoted pieces, are enough.

Hovering could perhaps show more pieces.

Oh yeah, we could have a sidebar that shows the pieces in the style we're hovering over.

Or maybe on hover change the displayed piece each second as long the user is hovering, or an option to pick what piece is displayed for all the piece sets, but some tooltip would be best probably. But since this isn't something that users do often, maybe it's fine the way it is.
Sidenote, probably better to have one css file with all the pieces as data-uri, instead of 20 or something separate requests, this file might be kinda big tho, if we decide to have several pieces displayed for each set.
