Title: Remove sample.env from generated apps

Naming the file Git stores `.sample.env` saves you potentially adding
malicious things into someone's foreman environment, but it doesn't prevent
you from storing things in your Git repo that shouldn't be, such as AWS keys.

Additionally, copying `.sample.env` to `.env` in `bin/setup` negates the
benefit of not just storing .env in the repository.
