Auto Refresh Posts when User Makes a New Post

Summary:
FbBroadcastManager.ReceiverBuilder will receive the corresponding broadcast from composer when user publishes a new post.
onReceive(Context context, Intent intent, BroadcastReceiverLike receiver) will be called after the post mutation is done, then we are safe to call mRecyclerCollectionEventsController.requestRefresh( to refresh the page. Later, mRecyclerCollectionEventsController.requestScrollToTop(true) when the load succeeded inside of LoadEventsHandler.
