    settings: Use _gtk_css_provider_load_named()
    
    This way we create one provider per settings object instead of stuffing
    it into a global unchanging never-deleting hash table.
    Also, we now reload the theme when instructed instead of keeping the old
    loaded (and possibly stale) data forever.
