What:

Move everything into their own packages

• emotion (core + aliases to the other packages for backwards compat until we do a major release)
• babel-plugin-emotion
• emotion-server
• emotion-utils (internal utils/stuff that's used across packages)
• react-emotion

emotion, emotion-utils and react-emotion have rollup builds with all their dependencies external so they're reused across the packages.
babel-plugin-emotion and emotion-server have babel builds

Why:

• ES Module builds
• Fixes issues like Module parse failed in emotion/src/index.js (12:19) and emotion/src/utils.js (3:5), unexpected token #258

How:

Checklist:

• Documentation
• Tests
• Code complete

I wrote a codemod to change the imports but I'm not sure where we should put it. Should we link to it? put it in the emotion package? another package? a folder in the repo?
