Michał Osadnik b7241bca22 Native event as a function (#83) ...

## Motivation 
I found it pretty fancy to write `nativeEvent` (or some field of `nativeEvent`) as a function which is evaluating on each event's frame.

## Changes
Because it must be done fully natively I do not relate `nativeEvent` function with  any View but use list of `AlwaysNodes` instead, which may seems to be similar to `Animated.Code` and behave conceptually in the same way.
On executing code it performs "evalution" which fill required (by function) fields of `nativeEvent` by `Animated.Value`s and connect it to `AlwaysNode`. I decided to use `Proxy` to manage it, but it is not supported currently by Android because of anscient version of JSC, which is going to be replaced soon (kindly ping @pmlocek), so I have done some kind of case-specic polyfill.
