GraphiQL Logo

I recently got a demo from @sgrove of the new GraphiQL features (explorer, code export) that he and @dwwoelfel are doing as part of the @OneGraph team, and that got me thinking that even though I benefit a lot from GraphiQL (it's packaged with [Vulcan.js](http://vulcanjs.org) so we use it daily), I never thought about contributing before.


So maybe a start could be giving the project its own logo? Here's something I whipped up quickly. It might be useful so help people distinguish between GraphQL and GraphiQL, since the names are already pretty similar. Of course if you think there's no need for a logo feel free to close this.
