Register one or more stylesheet files to be included when `symbol` is passed to `stylesheet_link_tag`. This method is typically intended to be called from plugin initialization to register stylesheet files that the plugin installed in `public/stylesheets`.

    ActionView::Helpers::AssetTagHelper.register_stylesheet_expansion :monkey => ["head", "body", "tail"]

    stylesheet_link_tag :monkey # =>
      <link href="/stylesheets/head.css"  media="screen" rel="stylesheet" type="text/css" />
      <link href="/stylesheets/body.css"  media="screen" rel="stylesheet" type="text/css" />
      <link href="/stylesheets/tail.css"  media="screen" rel="stylesheet" type="text/css" />
