Christoph Pojer a2c84d14ce Remove react-packager indirection.
Summary:
This moves the `src` directory one level up and removes the `react-packager` folder. Personally, I always disliked this indirection. I'm reorganizing some things in RNP, so this seems to make sense.

Not sure if I forgot to update any paths. Can anyone advice if there are more places that need change?
