title: Custom Ribbon Button doesn't show on subsites
body: <p>I've successfully added a custom ribbon button to my site and everything shows up as expected. However, when I go to a sub site, my custom ribbon button doesn't show up. How can I get my button to show up in the main site and also sub sites? I assumed that a button deployed to the main site would also carry over to sub sites but I guess that isn't the case. Anyone have any ideas or guidance? My button get's added to the "Media" group of the "Insert" tab for the RTE.</p>
  
  <p>Oh, and I am deploying this with a "Site" scoped feature.</p>
  
  <p>Here is my button code:</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;

          &lt;CommandUIExtension&gt;
              &lt;CommandUIDefinitions&gt;
                  &lt;CommandUIDefinition
                      Location="Ribbon.EditingTools.CPInsert.Media.Controls._children"&gt;
                      &lt;Button
                          Id="Ribbon.EditingTools.CPInsert.Media.Controls.MyCompany_InsertVideoButton"
                          ToolTipTitle="Video"

                          Command="MyCompany_InsertVideoButtonCommand"
                          TemplateAlias="o1" /&gt;
                  &lt;/CommandUIDefinition&gt;
              &lt;/CommandUIDefinitions&gt;
              &lt;CommandUIHandlers&gt;
                  &lt;CommandUIHandler

                  /&gt;
              &lt;/CommandUIHandlers&gt;
          &lt;/CommandUIExtension&gt;
      &lt;/CustomAction&gt;
  &lt;/Elements&gt;
