Ampersand(&) does not convert to &

If you are linking to a page that requires an "&" in the url Nice menus causes the xhtml to be invalid.

When rendering a menu item Nice Menus does not convert the & in the class attribute to &

This causes the page to be invalid xhtml

The Drupal menu module does this correctly, because it uses the same class for every menu item "leaf"

To duplicate simply add a menu item to two different menus (one Nice_menu, one normal) Enable both menus onto one page and look at the source.

I don't know if converting the "&" to "&" would solve the problem, or if the class attribute could just stop if it finds an "&"

I believe that an easy fix could be put around line 210 when the class is created:

      $path_class = 'menu-path-'. str_replace('/', '-', $menu['items'][$mid]['path']);

I did an ugly fix on my site:

	  $first_pass = str_replace('&', '&', $menu['items'][$mid]['path']);
      $path_class = 'menu-path-'. str_replace('/', '-', $first_pass);
