title: Make Menus in Wordpress use menu-item name instead of number for list item ID?
body: <p>So after calling <a href="http://codex.wordpress.org/Function_Reference/wp_nav_menu" rel="nofollow">wp_nav_menu</a> like:</p>
  
  <p><code>&lt;?php wp_nav_menu( array('menu' =&gt; 'Primary Menu' )); ?&gt;</code></p>
  
  <p>I end up with:</p>
  
  <pre><code>&lt;li id="menu-item-1"&gt;
  &lt;li id="menu-item-2"&gt;
  </code></pre>
  
  <p>... <code>id</code>s like <code>menu-item-1</code>, <code>menu-item-2</code>, etc. </p>
  
  <p>Is there some way to <strong>replace the numbers with the title of the page</strong> instead,so </p>
  
  <p><code>menu-item-1</code> becomes <code>menu-item-contact</code>, </p>
  
  <p><code>menu-item-2</code> becomes <code>menu-item-store</code>, etc?</p>
