jkachmar 647231b685 Yeet some default-extensions
Manually enables:
* EmptyCase
* ExistentialQuantification
* QuantifiedConstraints
* QuasiQuotes
* TemplateHaskell
* TypeFamilyDependencies

...in the following components:
* 'graphql-engine' library
* 'graphql-engine' 'src-test'
* 'graphql-engine' 'tests/integration'
* 'graphql-engine' tests-hspec'

Additionally, performs some light refactoring and documentation.
