Move HelloWorld template to a single index.js entry point Summary: This change (initially discussed in https://github.com/react-community/create-react-native-app/issues/26) moves the HelloWorld project template from two nearly identical entry points (`index.android.js` and `index.ios.js`) to a single, minimal `index.js` entry point. The root component is created in `App.js`. This unifies the project structure between `react-native init` and Create React Native App and allows CRNA's eject to use the entry point from the HelloWorld template without any hacks to customize it. Also examples in the docs can be just copy-pasted to `App.js` the same way in both HelloWorld and CRNA apps without having to first learn about `AppRegistry.registerComponent`. * Created a new project from the template using `./scripts/test-manual-e2e.sh` and verified that: * The app builds, starts and runs both on Android and iOS. * Editing and reloading changes works. * The new files (`index.js`, `App.js`, `__tests__/App.js`) get created in the project folder. <img width="559" alt="screen shot 2017-08-01 at 19 10 51" src="https://user-images.githubusercontent.com/497214/28835171-300a12b6-76ed-11e7-81b2-623639c3b8f6.png"> <img width="467" alt="screen shot 2017-08-01 at 19 09 12" src="https://user-images.githubusercontent.com/497214/28835180-33d285e0-76ed-11e7-8d68-2b3bc44bf585.png"> <!-- Thank you for sending the PR!

Use app name from app.json for registering application Summary: Currently when we change the app name in `app.json`, run `react-native eject` and then run the application, we get the following error `Application HelloWorld2 has not been registered` <img src="https://user-images.githubusercontent.com/6805530/34646396-9a68ccd0-f38c-11e7-9a49-9f985dc20f14.png" width="33%" /> This PR picks up the app name from app.json while registering the application, which prevents the additional step for the user to change the app name while registering in the `index.js` Tested using sinopia. The new app generated with the `react-native init HelloWorld` contains the changes made. [CLI] [ENHANCEMENT] [index.js] - App name picked from from app.json for registering application.
