Fixed #14675 -- Completed removal of from django.conf.urls.default import * usage.

This applies to both our own [test] code and documentation examples. Also:
 * Moved the functions and handlers from `django.conf.urls.defaults` up to
   `django.conf.urls` deprecating the former module.
 * Added documentation for `handler403`.
 * Tweaked the URLs topic document a bit.

Thanks to pupeno and cdestigter for their great work contributing patches.
