Changed Typings to @types/graphql (WIP)

[DxCx]

Also, had to align to latest graphql version (0.8.2).

I'm stuck in a module resultion issue which i don't have much time to get into,
if someone can help that can accelerate this PR..
Basiclly, because of the lerna's linking, it looks like typescript will include typings from node_module/@types of depended packages.
this leads to duplicate identifier on graphql:

                                                                                                                                                                                    [364/97369]

@DxCx could we solve this by updating all dependent packages that we have control over?

[DxCx]

We can align typed-graphql to @types and then it might work because graphql typings won't be on @types directory.
but it looks like @types/graphql is the one to be maintained for the long run.

@Urigo , @davidyaha do you have any insights on this issue before i'm going to deep dive into it?
looks like @types/graphql is being imported from siblings packages as well for some odd reason.

Closing this in favor of #260. Sorry we didn't see this PR @DxCx 😞
