Menu depth doesn't affect menu-item-has-children

[mikeybinns]

Hi,

When you add a depth of 1 to wp_nav_menu it removes all the sub menus, but it leaves menu-item-has-children class on the original menu li tags, which means it is styled like it has a dropdown.

Updated Patch.

These patches work for the first depth (the main line) but the class is also added to lower level submenus.

Example:

Depth = 1
<li class="no-class">
  <a>menu item</a>
</li>

Depth = 2
<li class="menu-item-has-children">
  <a>menu item</a>
  <ul class="sub-menu">
    <li class="menu-item-has-children">
      <a>2nd depth menu item with removed submenu</a>
    </li>
  </ul>
</li>

I think this needs some kind of depth iterator, so the function knows the max depth and the current item depth.

Thanks,
Mikey
