Animating the score display

When points are awarded, scale up the score display. Then scaleTo restores its original size over popDuration seconds. Stop the previous animation before starting another. BlockPuzzleScoreComponent.ts

this.killOwnedTweens();
this.node.setScale(this.baseScale * this.config.popScale);
this.ownTween(
  this.node.tweens.scaleTo(this.baseScale, this.config.popDuration, {
    ease: 'back.out(2)',
  }),
);
