Isolated extra components

[piranna]

Thhis pull-request remove all the react-native-web specific code and left only the extra modules so they can be used standalone. This way it's easier to get up with newer versions of upstream react-native-web. Also it removes deprecated Navigation component and update all the dependencies. Only missing part is to move react-pull-to-refresh module to an independent package instead of being blundled and update it to match upstream code and use latests dependencies. This is related to #2
