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.

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.

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.

26e2372c5e Fix value parsing
- Add missing variable parsing.
- Reuse `name` in value string.

This parses successfully the `kitchen-sink.graphql` sample from
`graphql-js`.

c0b6fc8a05 Replace take... functions with many...
They are less efficient but they are giving me issues because they don't
fail. Once this is working I'll look into optimizing.

Also disable skipping comments until I figure out how to skip both
comments and space at the same time.

62adfd89cd Several improvements to the parser
- Add token combinator to simplify whitespace handling.
- Simplify whiteSpace parsers.
- Add `optempty` to handle pure mempty cases. `empty /= pure mempty`.
- Use `between` combinators for brackets, braces and parens.

This also includes small adjustments to the AST.

44a2ff4765 Minor adjustments in AST for easier parsing
Also `Maybe` wrappers removed. I don't think there needs to be a special
case for empty values vs no values at all.
