    Template loaders defined before local settings

    TEMPLATE_LOADERS was defined after loading local_settings.py and was sqashing
    any attempt to customize the template loaders.
    This patch adds CACHED_TEMPLATE_LOADERS, ADD_TEMPLATE_LOADERS and a doc
    defining how to use them in order to ease customization process.
