title: MasterDetail ToolbarItem present in Detail
body: <p>I have a MasterDetailPage and I put a ToolbarItem in the parent controller, but it appears in the Detail as well. Any ideas why?</p>
  
  <pre><code>&lt;MasterDetailPage.ToolbarItems&gt;
      &lt;ToolbarItem Name="addMeterReading" Order="Primary" Icon="add.png" Text="Add Reading" Priority="0" Clicked="NewMeterReading_Clicked" /&gt;  
  &lt;/MasterDetailPage.ToolbarItems&gt;
  </code></pre>
