title: Detect if remote website is frameable
body: <p>I want to detect if remote website allows to stand under iframe or not.
  For example if website does not want to show content under iframe (amazon.com item details page) or if they have frame busting code (walmart.com) I do not want to bother with these websites. I just want to open new window, for others (like wikipedia.com) I want to show content under iframe.</p>
  
  <p>My question is that is there any way to detect if website will accept being under iframe or not?</p>
