nav menu - need to strip tags from item descriptions

[yoavf]

wp_setup_nav_menu_item( ) uses $menu_item->post_content as a fallback for $menu_item->description.

It needs to be stripped of tags or else the HTML might break the post editing menu

We should probably create filters for the menu fields and add them to the approproate places in default-filters.php.
