Update readme for renaming funtions

[pyrossh]

The docs/readme needs to be updated to specify that not all conventional input names follows graphql-relay js, Like the clientMutationId which is normally used in graphql-relay needs to be specified as clientMutationID graphql-relay-go.

Just updated my version to the latest.

I guess you need to update the blog post also?

Hi @pyros2097

Thanks for taking your time to look into this 👍🏻

Yeah you are right, the documentation is seriously lacking. I just updated the APIs for graphql-relay-go with the following changes

• update the import path for graphql-go to github.com/chris-ramon/graphql and its new APIs
• used golint suggestions for e.g. to use clientMutationID over clientMutationId.

I'll definitely would highlight the differences. My initial plan is to bring this library on par with graphql-relay-js v0.3.5 first (currently it is at v0.3.2). (Of course, I welcome PR contributions 😃)

Regarding the blog post, I've just updated it, thanks for the reminder! 👍🏻
