Enable babel transformer for emotion

Summary: This diff enables the babel transformer for emotion. It is supposed to be a bit faster, but the most interesting thing is that it will show component names inside the dom tree, which, at least for me, will be a huge performance booster is it will make it much easier to find out to which component style changes need to be applied
