transitioner2

Introducing a wild and hacky prototype of Transitioner 2!

- "transitionProps" concept is now identical to transitioner.state
- Far simpler state management than before
- Descriptors only, no "scenes"
- No more "position"

Also, StackView is seeing improvements:
- Easier to understand when "transition props" are just this.props

- StackView only renders the current sceen and the one before it

Currently broken:
- Interpolation configuration, beyond the first push
- Attempting to move away from getSceneIndicesForInterpolationInputRange because it works with position and it is confusing as hell, but haven't worked around it yet
- Gestures, although some "backProgress" code is in the works
- Interpolation is super buggy
- onTransitionStart/End
- Header, although a lot of code is moved over
