Media module compatibility - Look for the 'view media' permission as well.

Hello, first of thank you for the great module.

I'm currently working on a website with security restriction: the anonymous users can't see published content, but they have the right to see the website's medias (using the media module 'View media' permission)

Looking at the line 420 of bg_image.module:

  if (is_numeric($nid)) {
    // Load the node so we can check it's status
    $node = node_load($nid);
    // Check node access permissions
    if (node_access('view', $node)) {
      // Get the path of the image on the node
      $image_path = bg_image_get_image_path_from_node($nid);
      // Add the background image
      return bg_image_add_background_image($image_path, $css_settings);
    }
  }

All my site needs is another check on the media's 'view media' permission to make this possible.

  if (is_numeric($nid)) {
    // Load the node so we can check it's status
    $node = node_load($nid);
    // Load the current user.
    global $user;
    // Check node access permissions or on the 'view media' permission @see media module
    if (node_access('view', $node)||user_access('view media',$user)) {
      // Get the path of the image on the node
      $image_path = bg_image_get_image_path_from_node($nid);
      // Add the background image
      return bg_image_add_background_image($image_path, $css_settings);
    }
  }

And since your module only gets the content's media field, it seems fair to assume the security restriction is still respected. What do you think?
