title: multiple properties for facebook feed publishing attachment
body: <p>In the FBConnect.xproj, the feed string is as follows:</p>
  
  <pre><code>dialog.attachment = @"{\"name\":\"Facebook Connect for iPhone\",\"href\":\"http://developers.facebook.com/connect.php?tab=iphone\",\"caption\":\"Caption\",\"description\":\"Description\",\"media\":[{\"type\":\"image\",\"src\":\"\",\"href\":\"http://developers.facebook.com/connect.php?tab=iphone/\"}],\"properties\":{\"another link\":{\"text\":\"Facebook home page\",\"href\":\"http://www.facebook.com\"}}}";
  </code></pre>
  
  <p>The 'properties' section looks like this:</p>
  
  <pre><code>...\"properties\":{\"another link\":{\"text\":\"Facebook home page\",\"href\":\"http://www.facebook.com\"}}}"
  </code></pre>
  
  <p>I want to know, how can I do multiple properties? There is no explicit example in the Facebook SDK documentation. For example, I'd like this to show up:</p>
  
  <pre><code>another link: Facebook home page 
  yet another link: Twitter home page 
  AND another link: ESPN home page
  </code></pre>
  
  <p>I can't seem to get the bracket/comma placement correctly...has anyone accomplished setting multiple properties? Please show me how! Thank you! </p>
