remove useless config in setting.py for 0.9.10

[Deshi Xiao]

I have deploy graphite 0.9.10-pre1,
i found currently django setting is also can't work if only setting local_setting.py.
in django 1.4 environment, i should be modify setting.py
#Initialize database settings
DATABASES = {
    'default': {
        'NAME': os.path.join(STORAGE_DIR, 'graphite.db'),
        'ENGINE': 'django.db.backends.sqlite3',
    }
}

also we can remove useless code in above.
# Default sqlite db file
# This is set here so that a user-set STORAGE_DIR is available
if 'sqlite3' in DATABASE_ENGINE \
    and not DATABASE_NAME:
  DATABASE_NAME = join(STORAGE_DIR, 'graphite.db')

do you have any another option?

The local_settings.py.example file has a commented out example of the new config required for Django 1.4. We're still supporting Django 1.1 which doesn't read the new config style (it was introduced in Django 1.2) and additionally most of our users are still using the old-style database config style.

I looked for a solution that wouldn't break compatibility with older installs but still allow Django 1.4 to work with default settings, but the logic in settings.py became overly complex and ultimately it was deemed too risky. It was decided to err on the side of compatibility for this release. Next release, Django 1.1 support will be removed and we can default to the new style.

If you're working in settings.py, you should instead copy local_settings.py.example to local_settings.py and make your changes based on the comments there.
