title: createObjectURL does not work in ie10
body: <p>I am reading a base64 encoded file from indexedDB and trying to link to it as a blob url. The code below works fine in Chrome but when I click the link in ie10 nothing happens. I can see on the properties of the link that the href is blob:66A3E18D-BAD6-44A4-A35A-75B3469E392B which seems right. Anyone see what I'm doing wrong?</p>
  
  <p>Download Attachment</p>
  
  <pre><code>           //convert the base64 encoded attachment string back into a binary array
              var binary = atob(attachment.data);
              var array = [];
              for(var i = 0; i &lt; binary.length; i++) {
                  array.push(binary.charCodeAt(i));
              }
  
              //create a blob from the binary array
              var myBlob=new Blob([new Uint8Array(array)], {type: attachment.content_type});
  
              //create a url hooked to the blob
              downloadURL = (window.webkitURL ? webkitURL : URL).createObjectURL(myBlob);
  
              //set the attachment link to the url
              $('#attachmentLink').attr("href", downloadURL);
              $("#attachmentLink").text(fileName);
  </code></pre>
