770df82718 Simplify Schema definition API 
Now there is one `Resolver` type and the `Output` and `Scalar` types
have been removed. This should be closer to the final Schema definition
API.

8ee50727bd Overhaul Schema DSL 
Aside of making the definition of Schemas easier, it takes care of
issues like nested aliases which previously wasn't possible. The naming
of the DSL functions is still provisional.

a088c81944 Handle Field arguments in Schema definition 
The `Schema` has been overhauled to make `Output` monomorphic.
Traversing the `GraphQL` document is handled implicitly while defining
the `Schema`.

The 4th end-to-end test from `graphql-js` has been ported.

70fbaf359e Split Character data type into Droid and Human 
`Character` is now a synonym of the sum type of `Droid` and `Human`.

For now I don't see the need to implement GraphQL Schema interfaces with
type classes or lens. Plain Haskell ADTs should be good enough.

bb685c9afa Rough implementation of execute 
The first end-to-end test taken from `graphql-js` passes but this still
needs to be extended to support more general cases.

- `Data.GraphQL.Schema` has been heavily modified to support the
  execution model. More drastic changes are expected in this module.
- When defining a `Schema` ordinary functions taking fields as input are
  being used instead of maps. This makes the implementation of `execute`
  easier, and, arguably, makes `Schema` definitions more *Haskellish*.
- Drop explicit `unordered-containers` dependency. `Aeson.Value`s and
  field functions should be good enough for now.

899fa1b531 Handle escaped quotes for GraphQL String Values 
This also includes a new type for Value String.

The tests fail now, although it parses successfully. I'll use a pretty
printer in next commit so that it's easier to spot the differences.
Onces this is working I'll add the rest of the escaped characters.
