closes #927
depends on: DefinitelyTyped/DefinitelyTyped#12767

Currently getting a few errors with GraphQLError type as the @types/graphql is saying some fields are required. Some changes are needed before that gets merged and then this can be.

Just wanted to push some work before bed and someone else spends the same time on this :)

Also depends on this: DefinitelyTyped/DefinitelyTyped#12800 to fix GraphQLError usage in tests

[intellix]

That fixes all of the errors throughout compilation. I'm still getting errors about Namespace _ not having some exported members but that'll not be to do with anything I did.
When DefinitelyTyped#12800 is merged, this is good to go

Also requires: https://github.com/apollostack/graphql-anywhere/pull/16

[intellix]

all depended branches were merged. This should be ready to go

@intellix Awesome! Do you have time to rebase/merge the branch? As soon as that's done, we should be ready to drop typed-graphql.
