title: Remove "shipping subtotal" from Woocommerce's new order emails
body: <p>I have tried unsetting the code but then it removes totals too. I want to leave totals and remove shipping totals.</p>
  
  <pre><code>&lt;?php
      if ( $totals = $order-&gt;get_order_item_totals() ) {
          $i = 0;
          foreach ( $totals as $total ) {
              $i++;
              ?&gt;&lt;tr&gt;
                  &lt;th scope="row" colspan="2" style="text-align:left; border: 1px solid #eee; &lt;?php if ( $i == 1 ) echo 'border-top-width: 4px;'; ?&gt;"&gt;&lt;?php echo $total['label']; ?&gt;&lt;/th&gt;
                  &lt;td style="text-align:left; border: 1px solid #eee; &lt;?php if ( $i == 1 ) echo 'border-top-width: 4px;'; ?&gt;"&gt;&lt;?php echo $total['value']; ?&gt;&lt;/td&gt;
              &lt;/tr&gt;&lt;?php
          }
      }
  ?&gt;
  </code></pre>
  
  <p>I can't seem to find a solution for this. Any suggestions?</p>
  
  <p>Thanks.</p>
