Adds to Melange a tags framework based on taggable-mixin.
The taggable-mixin allowed only tag per Datastore model. This is extended
framework allows any arbitrary number of tags per Datastore model. Also,
now one can define different models for different Tag types which are all
inherited from the base Tag model provided by taggable-mixin.
The GHOPTask model makes use of 2 tags per model, one for difficulty and the
other for task_type, both using the tags framework.

Authenticating against Django's user database from Apache
=========================================================
Since keeping multiple authentication databases in sync is a common problem when
dealing with Apache, you can configuring Apache to authenticate against Django's
`authentication system`_ directly. For example, you could:
* Serve static/media files directly from Apache only to authenticated users.
* Authenticate access to a Subversion_ repository against Django users with
a certain permission.
* Allow certain users to connect to a WebDAV share created with mod_dav_.
Configuring Apache
==================
To check against Django's authorization database from a Apache configuration
file, you'll need to use mod_python's ``PythonAuthenHandler`` directive along
with the standard ``Auth*`` and ``Require`` directives::
<Location /example/>
AuthType basic
AuthName "example.com"
Require valid-user
SetEnv DJANGO_SETTINGS_MODULE mysite.settings
PythonAuthenHandler django.contrib.auth.handlers.modpython
</Location>
By default, the authentication handler will limit access to the ``/example/``
location to users marked as staff members. You can use a set of
``PythonOption`` directives to modify this behavior:
================================ =========================================
``PythonOption`` Explanation
================================ =========================================
``DjangoRequireStaffStatus`` If set to ``on`` only "staff" users (i.e.
those with the ``is_staff`` flag set)
will be allowed.
Defaults to ``on``.
``DjangoRequireSuperuserStatus`` If set to ``on`` only superusers (i.e.
those with the ``is_superuser`` flag set)
will be allowed.
Defaults to ``off``.
``DjangoPermissionName`` The name of a permission to require for
access. See `custom permissions`_ for
more information.
By default no specific permission will be
required.
================================ =========================================
Note that sometimes ``SetEnv`` doesn't play well in this mod_python
configuration, for reasons unknown. If you're having problems getting
mod_python to recognize your ``DJANGO_SETTINGS_MODULE``, you can set it using
``PythonOption`` instead of ``SetEnv``. Therefore, these two Apache directives
are equivalent::
SetEnv DJANGO_SETTINGS_MODULE mysite.settings
PythonOption DJANGO_SETTINGS_MODULE mysite.settings
