Use graphql-loader/tag or similar

I'd like if the entire schema existed as `schema.graphql` and used the `# import` references.

Yes, this means that the root `./src` or package should use `.babelrc` to make it work.

Honestly, the ideal would be for babel to only use transforms when using the source so that if we referenced the `dist/` version for tests (the ideal scenario), no side-effects will take place from Jest using babel.
