title: Rails: How to override stylesheet_path
body: <p>I've been trying to override Rails' <code>stylesheet_path</code> helper, but I haven't found a way how. I can't just open the <code>ActionView::Helpers::AssetTagHelper</code> module and override it there, because Rails won't pick up my new method.</p>
  
  <p>I know it's probably because the module gets mixed in, so how do I get around that?</p>
