Missing ability to tween more than two values per tween

[benPesso]

There are several cases where this would be convenient. For example, to fade a widget in and out, while also moving it from left to right, like this:

MultiTween()
  ..add('position', 0.0.tweenTo(100.0))
  ..add('opacity', 0.0.tweenTo(1.0).tweenTo(0.0))
