Function Drupal.shoutbox.loadShouts breaks on subdir Drupal installations

The loadShouts function makes AJAX calls to current domain root dir, regardless of where Drupal has been installed (see below). This behaviour breaks auto-refresh when Drupal is installed in a domain sub-directory.
The attached patch fixes the bug adding a "baseUrl" to the options hash.

Drupal.shoutbox.loadShouts = function() {
	$("#shoutbox-posts").load("/shoutbox/js/view");
