Using import_by_path to import import_by_path is a really odd use case
and makes the code example difficult to read.

Fix bug introduced in contrib.gis in 74f3884a

This starts the deprecation period for PIL (support to end in 1.8).

Recommend using the bcrypt library instead of py-bcrypt

Clarified what unique_for_date considers

Minor spelling fix

* py-bcrypt has not been updated in some time
* py-bcrypt does not support Python3
* py3k-bcrypt, a port of py-bcrypt to python3 is not compatible
  with Django
* bcrypt is supported on all versions of Python that Django
  supports

BCrypt on Python3

Excluded postgis specific gis tests from other spatial databases.

Refs #17365, #17366, #18727.

Refs #17365, #17366, #18727.

The origin statement "which could be ... or whatever" **misguides** many newbies like me.

In fact, the ``login`` function in ``contrib.auth`` stores ``user.pk`` in session, then ``get_user`` function in ``contrib.auth`` gets ``user.pk`` in session and then passes it to your custom ``get_user`` as ``user_id``.

Which means, ``user_id`` prarameter in your custom ``get_user`` has to be the primary key of ``User`` object, too.

Thanks to Preston Timmons for the bulk of the work on the patch, especially
updating Django's own test suite to comply with the requirements of the new
runner. Thanks also to Jannis Leidel and Mahdi Yusuf for earlier work on the
patch and the discovery runner.

Refs #11077, #17032, and #18670.

Added a test, the issue was already fixed (likely by the patch
for #19385).

Thanks Anssi for the review.

Thanks Julian Wachholz for the report.

This also updates all dependent functionality, including modelform_factory
 and modelformset_factory, and the generic views `ModelFormMixin`,
 `CreateView` and `UpdateView` which gain a new `fields` attribute.
