user data added to context

[dabit1]

With this PR we'll be able to get the decoded user data from context. So in the resolvers we can get user data like this:

me: (parent, args, { user }) => {
      console.log(user.id);
},

Merge please, then we can make @user directive

This needs to be updated in the README.md file
