Implement support for AMP web stories within Acorn

Integrate support for Wagtail Stories. AMP is an emerging standard for web-component based websites, and could represent the first step toward a fully headless system.

• Research what it will take to implement Wagtail Stories as a supported application for Acorn
• Read documentation and determine how web stories can be integrated into existing pages
  • Embed a web story as part of a slider/carousel
  • Add a story in a column layout that when clicked loads the web story as a lightbox
