Copy the replay file into the repo

Cookiecutter saves a replay file (oddly) in
`~/.cookiecutter_replay/cookiecutter.json` that can be later used with
`--replay --replay-file` to regenerate the template without having to
enter all the inputs again.  We save this file in the repo to make it
easier to fetch future updates to the templates.
