[v0.4.7b0] graphql-core v0.4.7-beta-0 release

This is the first beta release of graphql-core and represents feature parity with graphql-js v0.4.7, hence the matching version number. All graphql-core releases will follow graphql-js in terms of version numbers. This means for a given version of graphql-js, you can expect feature parity on the same version of graphql-core.

We will follow GraphQL's semantic versioning and releases except for one key difference, we will be introducing a BUGFIX version number as well, in the form of MAJOR.MINOR.PATCH.BUGFIX. This will allow us to match the PATCHes in graphql-js, while maintaining our own bugfix version numbers. That means that v0.4.7.0, v0.4.7.1 will all match v0.4.7 in feature parity, but with bugfixes to the Python codebase.
