`<paper-icon-item>` is a convenience element to make an item with icon. It is an interactive list
item with a fixed-width icon area, according to Material Design. This is useful if the icons are of
varying widths, but you want the item bodies to line up. Use this like a `<paper-item>`. The child
node with the attribute `item-icon` is placed in the icon area.

    <paper-icon-item>
      <iron-icon icon="favorite" item-icon></iron-icon>
      Favorite
    </paper-icon-item>
    <paper-icon-item>
      <div class="avatar" item-icon></div>
      Avatar
    </paper-icon-item>
