Minor Changes

• Add Accept header to GraphQL HTTP requests. This complies to the specification but doesn't go as far as sending Content-Type which would throw a lot of APIs off. Instead, we'll now be sending an accept header for application/graphql+json, application/json to indicate that we comply with the GraphQL over HTTP protocol.
  This also fixes headers merging to allow overriding Accept and Content-Type regardless of the user options' casing, by @kitten (See #2457)

Patch Changes

• Support aborting in withPromise cases, by @JoviDeCroock (See #2446)
• Passthrough responses with content type of text/* as error messages, by @kitten (See #2456)
