Adds a new state persistence mechanisms to all of the navigators via createNavigationContainer
There are two new props that you can provide to a navigation container: `storageKey` and `renderLoading`.
`storageKey` is the string key to be used with AsyncStorage while saving and persisting navigation state. To disable persistence, set to null.
`renderLoading` allows you to render something while the navigator re-hydrates its state and loads its initial URL. By default this returns null, but Expo users will want to render a <AppLoading /> component for smooth app launches
There is also functionality in this PR to observe errors that come from re-hydrating state, and gracefully recover by dispatching an init action.
Also this revises the init action to *reset* the navigation state, rather than preserve the previous state.
