title: How do I "unlike" a built-in like in a single request?
body: <p>When you want to "unlike" a built-in like action on an open graph object, you have to send an HTTP <code>DELETE</code> with the id of the like story itself. But that requires either:</p>
  
  <ol>
  <li>Querying the graph for the ID of the story before deleting it, or</li>
  <li>Stashing the ID that's returned when you create the like in the first place.</li>
  </ol>
  
  <p>Neither of these are satisfying solutions. It would be nice to be able to do this all in a single request, preferably with nothing more than the URL of the liked object.</p>
  
  <p>Because this modifies the graph, the Graph API has to be used, right? AFAIK, FQL is still read-only.</p>
