title: How to retrieve file content from Javascript readEntries()
body: <p>I'm implementing a directory drag and drop on my web application, I receive the event and get the corresponding <code>entry</code> by calling <code>webkitGetAsEntry()</code>. Then I check the <code>entry</code> object: if it's a directory I proceed to list all the files.</p>
  
  <pre><code>  var entry = event.originalEvent.dataTransfer.items[0].webkitGetAsEntry();
    if (entry.isDirectory) {
          var reader = entry.createReader();
          reader.readEntries(function(entries){
          entries.forEach(function(entry) {
                alert(entry.fullPath);
          });
    });
  </code></pre>
  
  <p>At this point I'm able to get only the filename, what I'd like to have is also the file content but apparently the array returned by <code>readEntries()</code> doesn't include it</p>
