Added markup for lists and switches

@samjoch please check in template:
      <li>
        {{#if icon}}
          <span class="icon icon-{{icon}}">icon-{{icon}}</span>
        {{/if}}
        <span class="content"><content></content></span>
        {{#if switched}}
          <span class="switch {{switched}}">{{switched}}</span>
        {{/if}}
      </li>
