Ensure Specification(June 2018) Compliance (#631)
* Implemented most test cases from the specification
* Unified error handling for all generators
- Removed proc-macro-error -> not required -> use syn::Error
- Everything below lib.rs uses proc_macro2::TokenStream
instead of proc_macro::TokenStream
- Replaced error handling in attribute parsers
* WIP better error messages for *all* macros
* Refactored GraphQLInputObject and minor tweaks
- removed support for Scalar within a string ("DefaultScalarValue")
- removed unraw function and replaced it with the built-in one
- added error messages and return types for all functions within utils
- added more constraints to fulfill the GraphQL spec
* Fixed test-cases which are not compliant with the specification
* Removed unused function
* Added constrains, updated error messages, added marker
* Added argument rename within impl_graphql and fixed `__` tests
* Formatted and cleanup
* Added GraphQLTypeAsync for input object
* Moved codegen tests to separate module
Nightly and stable produce different outputs, thus only test nightly.
* Added IsInputType/IsOutputType traits for type checking
