amp-react-components

Render AMP components with React.

1. Support styled-components by passed-in className prop.
2. Attaches className prop to class prop of AMP elements for supporting HTML class attribute. Now React does't support custom element attributes, so the <amp-img className="img" /> will be rendered as <amp-img classname="img" />
3. Render script tag with type=application/json to support AMP components, such as amp-animation and amp-bind
