deprecated CACHE_* statement in local_settings.py.example

[Matthias Runge]

the cache syntax changed to something like: {
    'default': {
        'BACKEND': 'django.core.cache.backends.locmem.LocMemCache',
    }
}
At every start, you'll get a warning DeprecationWarning: settings.CACHE_* is deprecated; use settings.CACHES instead
