Module rewrite to give more structured data,

Hi,

It seems that we were working on the GraphQL module at the same time. I have built a much more comprehensive version which uses the config schema to build object which can be accessed much easier. Such as if we are using the `text_format` config it will not only give you access to the text and the formatter, it will also give you a virtual field which will give you the processed text, the same as if you were reading the `body` field from an entity.

Also since there is so much very sensitive data held in the config I have made it so that the config items exported to graphql are very restricted and only have items which are set in the settings.php.
