Add support for block strings

[frasercobb]

Hello,
This is a feature request to support "Block Strings" as per the spec: https://facebook.github.io/graphql/June2018/#sec-String-Value

I have reproduced this issue in the starwars example in this repo.

Example mutation that will trigger this issue:

mutation {
  createReview(episode:NEWHOPE, review: {stars: 0, commentary: """1
    2"""}) {
    stars
  }
}

Response:

{
  "errors": [
    {
      "message": "syntax error: unexpected \"\\\"1\\n\", expecting Ident",
      "locations": [
        {
          "line": 31,
          "column": 66
        }
      ]
    }
  ]
}

Log output: <input>:31:66: literal not terminated

Thanks for reporting!

I believe this has since been resolved by #269 ? Requires an opt-in option (UseStringDescriptions()) to be applied when creating the schema.

You are right, Dave. I'm closing this issue.
