Issue:
Replay does not get correct user config
I think we need to persist the currently chosen config file so that subsequent calls of ``config.get_user_config`` yield the same values for the session.

Currently **cookiecutter/replay.py** always points to ``os.path.expanduser('~/.cookiecutter_replay')``:

```python
replay_dir = get_user_config()['replay_dir']
```

Pull request description:
Pass user config to replay
Change the signature of both ``replay.load`` and ``replay.dump`` to require a replay directory opposed to retrieving it from ``config.get_user_config()``.

Resolve #590
