Typo in Chapter 3.6

In the **Creating a new Django App** section, there is a typo in the file name, it reads `view.py` but should read `views.py`:

```diff
-5.  In your app's `view.py`, create the required views ensuring that they return a `HttpResponse` object.
+5.  In your app's `views.py`, create the required views ensuring that they return a `HttpResponse` object.
```
