Add tabletop components 486-500 and ten game icons

Fifteen pieces of a games night: Dice, DiceTray, PlayingCard, CardHand,
Deck, Chessboard, GoBoard, MahjongTile, Domino, Roulette, CoinFlip,
BingoCard, TicTacToe, ScoreTrack and Meeple. Component number 500 is
a meeple, which seems right.

Dice tumble, coins turn and wheels spin on a cue, a frame at a time,
and land at once under Reduce Motion. Hands lift the card you point
at and play the one drawn on top; pieces and stones pick the lighter
of Lit and Ink for White, so they read in every palette; the computer
plays a fair O; FREE is a star in every language.

New 12x12 icons: Spade, Club, Diamond, Meeple, King, Queen, Rook,
Bishop, Knight and Pawn.
