Title: Include pretender for non-production builds by default.

* Add pretender by default for non-production builds.
* Allow opting out with `includePretender: false`.
* Tests:
* Add test to confirm a default install in development has `Pretender` available.
* Add test to confirm that `Pretender` is **not** generated in production.
* Add test to confirm that `includePretender: false` actually works.
