[Plugin: JSON API] Extending save features: thumbnail and scheduled posts

I needed to mark the uploaded image as the post thumbnail so altered the save method with this:

if (!empty($_FILES['attachment'])) {
      include_once ABSPATH . '/wp-admin/includes/file.php';
      include_once ABSPATH . '/wp-admin/includes/media.php';
      include_once ABSPATH . '/wp-admin/includes/image.php';
      $attachment_id = media_handle_upload('attachment', $this->id);
      $this->attachments[] = new JSON_API_Attachment($attachment_id);

      if (isset($values['thumbnail'])) {
      	if($values['thumbnail'] == 'TRUE'){
      		$thumbnail_html = wp_get_attachment_image( $attachment_id, 'thumbnail' );
				if ( !empty( $thumbnail_html ) ) {
					update_post_meta( $this->id, '_thumbnail_id', $attachment_id );
				}
			}
		}

      unset($_FILES['attachment']);
    }

I also added scheduled posts with:

if (!empty($values['status'])) {
      $wp_values['post_status'] = $values['status'];

      	if (!empty($values['date']) && $values['status'] == 'publish') {
      		$wp_values['post_date'] = $values['date'];
    	}
    }

Thanks for a fantastic plugin Dan.
