Making a Gatsby Events List Starter

I made a basic events list Gatsby Starter, forked from the [Gatsby blog starter](https://github.com/gatsbyjs/gatsby-starter-blog). See it in action at [gatsby-starter-events-list.netlify.com/](gatsby-starter-events-list.netlify.com) and check out the code [on Github](https://github.com/johnpolacek/gatsby-starter-events-list).
