Add https://github.com/OneGraph/graphiql-explorer to the GraphiQL view.

I needed to make some tweaks to graphiql-explorer in order to make it work: OneGraph/graphiql-explorer#22

We should probably wait for them to merge this PR. If we bump the JS dependencies, it will not work anymore.

Another possibility would be to do it the way they do it in their "self-hosted" example (https://github.com/OneGraph/graphiql-explorer-example/blob/master/src/App.js) - just storing the schema in a state variable, which the fetcher updates. Just in case they don't merge the PR 😉

@lukasluecke Yes I know but the issue here is that you need to use the graphql package if you do it that way. And there is no minified version of it: you have to use it in a Webpack context, which is not our case (it would require some work to introduce it).
