Cleaner walker for navigation menus

Walker_Nav_Menu (WordPress default) example output:

  <li id="menu-item-8" class="menu-item menu-item-type-post_type menu-item-object-page menu-item-8"><a href="/">Home</a></li>
  <li id="menu-item-9" class="menu-item menu-item-type-post_type menu-item-object-page menu-item-9"><a href="/sample-page/">Sample Page</a></li>

Soil’s NavWalker example output:

  <li class="menu-home"><a href="/">Home</a></li>
  <li class="menu-sample-page"><a href="/sample-page/">Sample Page</a></li>
