title: Scrapy custom settings
body: <p>Using <code>scrapy</code>, I have in one of my spiders:</p>
  
  <pre><code>class IndexSpider(scrapy.Spider):
      name = "indices"
  
      def __init__(self, *args, **kwargs):
          super(IndexSpider, self).__init__(*args, **kwargs)
  
          # set custom settings
          custom_settings = {
              'DOWNLOAD_DELAY': 2,
              'ITEM_PIPELINES': {
                  'freedom.pipelines.IndexPipeline': 300
              }
          }
  </code></pre>
  
  <p>However, when I later try to access the settings via</p>
  
  <pre><code>    print(dict(self.settings.get('ITEM_PIPELINES')))
  </code></pre>
  
  <p>they are empty. Background is that I want to control the settings (and possible pipelines) on a per-spider basis.<br>
  What am I doing wrong here?</p>
