5.0.0

• Bump minimum Node version to 4.0 (6e2a0db)
• Fix a yosay bug (7bef882) The prompts were showing up in the middle of the yosay speech bubble for some reason.
• Update overall structure, add babel static class method plugin (eb82fc4)
  1. added src/ at the root of every project to keep your working files clean and separate from everything else
  2. merged the sanitize stylesheet into the top-level style.styl
  3. updated various files with newer ES6+ conveniences
  4. added the babel "transform-class-properties" plugin to enable static class property shortcuts (part of the enhancements in #3)
  5. removed the LICENSE file in favor of the simple license field in package.json
  6. reorganized where static assets are meant to live; place your images, fonts, etc in src/static/assets and they will be copied over to /dist during the build process
  7. switched the dev server (budo) invocation from the CLI to using it as a library; see scripts/budo.js
