- patch to recognize django variables right from the ``DEFAULTS`` sectio...

thanks for your lib, we like it! :) 

i discovered an issue if you have this config::

	# Default values for all apps
	# Can be overridden within the app-section with: ``set var=value``
	[DEFAULT]
	debug = false
	django_settings_module = inventorum.api.settings
	admin_email = tech@inventorum.com
	STATIC_URL = "/static/"
	VAR_ROOT = %(here)s/../../var

	# http://pythonpaste.org/deploy/#composite-applications
	[composite:main]
	use = egg:Paste#urlmap
	/ = inventorum_api_app


	# main app
	[app:inventorum_api_app]
	use = egg:inventorum.api#api_main

	set debug = true
	TEMPLATE_DEBUG = ${debug}
	SESSION_COOKIE_DOMAIN = "127.0.0.1"

in ``setup.py`` of our application i have::

    #!/usr/bin/env python
    from setuptools import setup, find_packages
    
    entry_points = """\
    [paste.app_factory]
    api_main = inventorum.api:make_api_application
    
and the matching bootstrap function looks like this:: 

    def make_api_application(global_config, **local_conf):
    
        # Do something before importing Django and your settings have been applied.
        log.debug('create django wsgi app ...')
        app = get_configured_django_wsgi_app(global_config, **local_conf)
    
        # Do something right after your application has been set up (e.g., add WSGI middleware).
        # http://rhodesmill.org/brandon/2011/wsgi-under-cherrypy/
    
        debug_flag = global_config['debug'] == 'true' or False
        log.debug('add ErrorMiddleware with debug: %s ...', debug_flag)
        app = ErrorMiddleware(app, debug=debug_flag)
        log.debug('add TransLogger with debug: %s ...', debug_flag)
        app = TransLogger(app, setup_console_handler=debug_flag)
        return app
    
now without this patch, the settings variable ``VAR_ROOT`` will not get published to djangos settings as it probably should (at least in my case). 

are you fine with that, any other requirements or did i do something wrong?

best, andi
