title: jQuery .scroll() events for the body/window/html/document
body: <p>I need a cross-browser way of binding to the scroll event for the browser's native scrollbar.</p>
  
  <p>$("html, body") seems to work for firefox, while $(window) seems to work for IE.</p>
  
  <p>Is there a better way to use the correct version rather than trial and error? I also would like to detect mobile scrolling, if possible.</p>
