  * The new method uses an admin configuration option (`formfield_overrides`); this makes custom admin widgets especially easy.
  * Refactored what was left of `formfield_for_dbfield` into a handful of smaller methods so that it's easier to hook in and return custom fields where needed.
  * These `formfield_for_*` methods now pass around `request` so that you can easily modify fields based on request (as in #3987).

Fixes #8306, #3987, #9148.

Thanks to James Bennet for the original patch; Alex Gaynor and Brian Rosner also contributed.

Previous behaviour was pretty stupid. Let's never speak of it again. New
behaviour both works and is documented.

Returning non-ASCII characters from TextNode.__repr__ was causing
problems in the BlockNode.__repr__ method (and probably in other places
we don't know about yet). We now forcibly convert to ascii and replace any
unconvertible characters, rather than returning some moderately
corrupted data in the non-ASCII case.

Fixed #8138 -- Changed django.test.TestCase to rollback tests (when the database supports it) instead of flushing and reloading the database.   This can substantially reduce the time it takes to run large test suites.

This change may be slightly backwards incompatible, if existing tests need to test transactional behavior, or if they rely on invalid assumptions or a specific test case ordering.  For the first case, django.test.TransactionTestCase should be used.  TransactionTestCase is also a quick fix to get around test case errors revealed by the new rollback approach, but a better long-term fix is to correct the test case.  See the testing doc for full details.

Many thanks to:
* Marc Remolt for the initial proposal and implementation.
* Luke Plant for initial testing and improving the implementation.
* Ramiro Morales for feedback and help with tracking down a mysterious PostgreSQL issue.
* Eric Holscher for feedback regarding the effect of the change on the Ellington testsuite.
* Russell Keith-Magee for guidance and feedback from beginning to end.

This *is* backwards compatible, but `admin.site.root()` has been deprecated. The new style is `('^admin/', include(admin.site.urls))`; users will need to update their code to take advantage of the new customizable admin URLs.

Also documented the change. We prefer to load directory_index.html for static
directory listings, but if you have the (older style) "directory_index"
template and no .html version, we'll load that. This should stop a bunch of
mysterious breakages when people upgrade to Django 1.0.3 or Django 1.1. Also
keeps the docs in sync with released code.
