2.0.0

Backwards incompatible changes:

• Drop support for Django 1.4
• Add support for Django 1.9
• Added new Django 1.9 migration for userena and userena.contrib.umessages.
  Old South migrations are still available in userena.south_migrations and
  userena.contrib.umessages.south_migrations but are deprecated and may be
  removed in future major releases. South>1.0 is required for older versions
  of Django.
• django-guardian requirement bumped to <=1.4.1 as newer version (1.4.2)
  fails on tests.
• removed all {% load url from future %} from userena templates for
  compatibility with Django 1.9
• sha_constructor(), smart_text(), and md5_constructor removed from
  userena.compat
• Use simple list literal as url patterns instead of
  django.conf.urls.patterns() function

Deprecated features:

• userena.utils.get_user_model is deprecated and will be removed in version
  3.0.0. Use django.contrib.auth.get_user_model

Fixes and improvements:

• More nodes added to the travis test matrix.
• Some documentation moved to .md files.
• Deprecated unittest aliases replaced in tests.
• Updated list of trove classifiers.
• Added option to execute runtests script with pattern parameter to limit
  number of tests.
• Added {posargs} to test command execution in tox.ini to improve developer
  experience during tests.
• Minor documentation improvements.
• Set django-guardian<1.4.0 version for Django 1.5 and 1.6 tests.
