* Allow for manual removal of dependencies to support advanced sandbox users who explicitly want to avoid compiling certain dependencies
  they know they aren't using.

  configuration with all of the package dependency flags enabled.

* Will now build as full-fledged `Safe` Haskell if you configure with -f-hashable.

* Added some missing `Generic`/`Generic`/`Hashable` instances
