Add callouts and logo

Created by: selbekk

This pull request simplifies the front page of the docs a bit, as it contained a few sections we don't need for a first release.

The React logo was borrowed from the template folder - I guess it's fine to duplicate like this?

Not sure about the Travis failure https://travis-ci.org/facebook/create-react-app/jobs/438291393#L2874, but it seems like it can be merged to docusaurus

Yeah all of my PRs have failed their Travis check, but it doesn't look like anything related to my code.

Merging then :)
