support Date type by default

[capaj]

currently if you want to handle dates correctly for a field, you need to explicitly use a scalar, like this:

  @Field({ type: GraphQLDateTime })
  created_at: Date

since this is very common-it would be great to enable this behavior by default, so you can omit the explicit type:

  @Field()
  created_at: Date

Sadly - currently typescript reflect api does not recognize dates: http://blog.wolksoftware.com/decorators-metadata-reflection-in-typescript-from-novice-to-expert-part-4

If it's changed - would be great to add such feature

It's not true 😉
TypeStrong/ts-node#511

There's was a bug with TypeScript compiler api that is used programatically like by ts-jest but it's reported to be fixed:
kulshekhar/ts-jest#439

awesome @19majkel94! Will take a stab at implementation.

I did make it work in my namespaced fork of typegql: capaj@19a9dd5

I attempted the same in this repo and it ended up in error while building:

$ ttsc --project ttsconfig.json
/home/capaj/git_projects/graphql-repos/typegql/node_modules/typescript/lib/tsc.js:114358
})(ts || (ts = {}));

error Command failed with exit code 1.

also jest infer test failed as well. Maybe jest is still running some old version of typescript? Not sure.

I can't really open a PR from my fork, because it has those DuplexTypes and some of other changes. So I guess it's up to you @pie6k
