f35e1f949a Define Schema using Core AST
Also, temporarily remove error reporting to simplify execution. This should be
restored once the new execution model is nailed.

5390c4ca1e Split AST in 2
One AST is meant to be a target parser and tries to adhere as much as possible
to the spec. The other is a simplified version of that AST meant for execution.

Also newtypes have been replaced by type synonyms and NonEmpty lists are being
used where it makes sense.

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.

98d2d41cda Initial support for variable substitution
The correspondent end-to-end test has been ported. The variable
definition still needs to be checked.

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.

df8e43c9aa Handle Output enumerations in Schema definition
The third end-to-end test from graphql-js was implemented.

eca3c2d8d4 Generalize Maybe type constructor to any Monad
This allows schema definitions with side-effects for any type with a
Monadic/Alternative implementation like IO for example.

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.
