Also removed support for passing a 3-tuple to include() and support for
setting an instance namespace without an application namespace.
Thanks Marten Kenbeek for completing the patch.
Made URL application namespaces be set in the included URLconf and
instance namespaces in the call to include(). Deprecated other ways
to set application and instance namespaces.
Propagated unnamed arguments as positional arguments into included
URLconfs if no named arguments are defined. Positional and keyword
arguments are never combined.
- Fixed bug in get_callable() that caused resolve() to put a string
in ResolverMatch.func.
- Made ResolverMatch.url_name match the actual url name (or None).
- Updated tests that used the string value in ResolverMatch.func, and
added regression tests for this bug.
- Corrected test urls whose dummy view paths caused failures (behavior
that was previously masked by this bug).
