Context

Some people are struggling with writing in markdown so it would be great to offer a simple rich text editor.

I'm a big fan of Medium so I've taken most of the inspiration from there.

This paired with the shortcuts suggested by @xiaoniuniu89 (#190) would make an awesome experience.

Note

I think this might be split into a few PRs and connected when it's all done so we can incrementally improve while getting ready for production.

As discurssed with @xiaoniuniu89 we are going to try and use https://www.slatejs.org/ and see where it goes.
