This requires all AnimationController objects to be given a TickerProvider, a class that can create the Ticker. It also provides some nice mixins for people who want to have their State provide a TickerProvider. And a schedulerTickerProvider for those cases where you just want to see your battery burn. Also, we now enforce destruction order for elements.
