Rename project_name to config inside project_name dir

[angvp]

When I set-up an app (translationtest in this case) I have the following dir structure:

.
├── fabfile.py
├── README.rst
├── requirements.pip
├── server_conf
│   ├── nginx.conf
│   └── uwsgi.ini
├── translationtest
│   ├── apps
│   │   └── __init__.py
│   ├── manage.py
│   ├── static
│   │   ├── css
│   │   │   ├── bootstrap.css
│   │   │   ├── bootstrap.min.css
│   │   │   ├── bootstrap-theme.css
│   │   │   ├── bootstrap-theme.min.css
│   │   │   └── style.css
│   │   ├── fonts
│   │   │   ├── glyphicons-halflings-regular.eot
│   │   │   ├── glyphicons-halflings-regular.svg
│   │   │   ├── glyphicons-halflings-regular.ttf
│   │   │   └── glyphicons-halflings-regular.woff
│   │   └── js
│   │       ├── bootstrap.js
│   │       └── bootstrap.min.js
│   ├── templates
│   │   ├── 404.html
│   │   ├── 500.html
│   │   ├── base.html
│   │   └── registration
│   │       ├── activate.html
│   │       ├── activation_complete.html
│   │       ├── activation_email_subject.txt
│   │       ├── activation_email.txt
│   │       ├── registration_closed.html
│   │       └── registration_complete.html
│   └── translationtest
│       ├── __init__.py
│       ├── settings
│       │   ├── base.py
│       │   ├── __init__.py
│       │   ├── local.py
│       │   └── local.py.example
│       ├── urls.py
│       └── wsgi.py
└── var

12 directories, 34 files

So my proposal is to rename the last project_name dir inside project_name/project_name to something else, for instance config could be a good name because this dir contains settings files, but also contains the urls.py and wsgi.py files

Also having a different name reduce the noise when you're diving into the dirs/subdirs.

I will make a pull request with this change anyway, but I'd like to hear any opinions with this.
