makemessages should now automatically distribute translatable
strings in the proper locale files, for Django too
(see 50a8ab7c).

Fixed #22635 -- Make "It worked!" page localizable

Dutch ('nl-NL' and 'nl-BE') has several valid input formats;
see http://nl.wikipedia.org/wiki/Datum_(dagtekening).

Thanks Erik Romijn for review.

The `wordwrap` tests were in the `test_wordcount()` method for some
reason. This moves them to their own method, and make consistent use of
double quotes where needed.

This fixes a failing test after applying an optimization of the
utils.text.wrap function by user SmileyChris.

The tests would error out with an ImproperlyConfigured error
if the user had psycopg installed but not geos.
Thanks to mcgohier for the report.

Previously, class lookups from the output_type would be used, but any
changes to custom_lookup or custom_transform would be ignored.

Fixed #21905 -- Add info message if DateField or TimeField use a fixed value

Workaround for now, Andrew will look into it.

Exceptions from the (receiver, exception) tuples returned by
``send_robust()`` now have always their traceback attached as their
``__traceback__`` argument.

Also added tests with pytz and removed misplaced tests.

Also added tests for is/make_aware/naive.

Thanks Tom Michaelis for the report.

Authorization backends can now raise PermissionDenied in "has_perm"
and "has_module_perms" to short-circuit authorization process.

Clarified the explanation on the order in which user provided variables
to render_to_response, RequestContext and context processors are
loaded.

Now this method is only called only if the object is an instance.
This allows to have field classes as model class attributes.

This is the default now, see https://bitbucket.org/pypa/wheel/commits/c29f82b4cf76df71f8d55b0f825af6063d3b9892

While Node class has a useful `__str__`, its `__repr__` is not that
useful. Added a `__repr__` that makes use of the current `__str__`.
This is especially useful since the more popular `Q` class inherits
`tree.Node`. Also created new tests that cover most of `Node` class
functionality.

It was previously used in a test that was deprecated and then removed, this cruft can be removed now.

Thanks to Claude Paroz for the report and patch and Tomasz
Paczkowski for the review.
