Getting Start docs specify nonexistent development.ini

[The "Creating a Sysadmin User" portion of the "Getting Started" documentation](http://docs.ckan.org/en/latest/maintaining/getting-started.html#create-admin-user) specifies invoking paster with `paster sysadmin add seanh -c /etc/ckan/default/development.ini`. This does not work in a package installation, as the package doesn't include a `development.ini` file. Instead, it includes only:

```bash
$ ls /etc/ckan/default
apache.wsgi  production.ini  who.ini
```

I was able to proceed with `paster sysadmin add seanh -c /etc/ckan/default/production.ini`.

The fix is, presumably, to either specify the correct filename in the documentation or to include `development.ini` in the in `http://packaging.ckan.org/python-ckan-2.0_amd64.deb`.
