unicode: Changed all tests and documentation to use __unicode__ instead of

__str__ in places where it's appropriate to do so.

+``__unicode__``
+---------------
+
+The ``__unicode__()`` method is called whenever you call ``unicode()`` on an
+object. Since Django's database backends will return Unicode strings in your
+model's attributes, you would normally want to write a ``__unicode__()``
+method for your model. The example in the previous section could be written
+more simply as::
+
+    class Person(models.Model):
+        first_name = models.CharField(maxlength=50)
+        last_name = models.CharField(maxlength=50)
+
+        def __unicode__(self):
+            return u'%s %s' % (self.first_name, self.last_name)
+
+If you define a ``__unicode__()`` method on your model and not a ``__str__()``
+method, Django will automatically provide you with a ``__str__()`` that calls
+``__unicode()__`` and then converts the result correctly to a UTF-8 encoded
+string object. This is recommended development practice: define only
+``__unicode__()`` and let Django take care of the conversion to string objects
+when required.

+.. admonition:: Why ``__unicode__`` and not ``__str__``?
+
+    If you are wondering why we add a ``__unicode__()`` method, rather than a
+    simple ``__str__()`` method, it is because Django models will contain
+    unicode strings by default. The values returned from the database, for
+    example, are all unicode strings. In most cases, your code should be
+    prepared to handle non-ASCII characters and this is a litle fiddly in
+    ``__str__()`` methods, since you have to worry about which encoding to
+    use, amongst other things. If you create a ``__unicode__()`` method,
+    Django will provide a ``__str__()`` method that calls your
+    ``__unicode__()`` and then converts the result to UTF-8 strings when
+    required. So ``unicode(p)`` will return a unicode string and ``str(p)``
+    will return a normal string, with the characters encoded as UTF-8 when
+    necessary..
