title: Qt Creator `.pro.shared` files don't seem to have any effect
body: <p>I'm using Qt Creator 2.6.0 on Mac OS 10.8.2, and I've created a <code>myproject.pro.shared</code> file in the same folder as <code>myproject.pro</code>.  I copied the example XML from <a href="https://qt-project.org/doc/qtcreator-2.6/creator-sharing-project-settings.html" rel="nofollow">https://qt-project.org/doc/qtcreator-2.6/creator-sharing-project-settings.html</a> to the <code>myproject.pro.shared</code> file.  I deleted my <code>~/.config/QtProject/</code> folder and I do not have a <code>myproject.pro.user</code> file.</p>
  
  <p>When I launch Qt Creator and open the project file, the settings specified in <code>myproject.pro.shared</code> are not used.  For example, <code>myproject.pro.shared</code> specifies <code>TabSize</code> of 14, yet under Projects > Editor, "Editor settings" still says "Global", and Tab size is not 14.</p>
  
  <p>How can I get this working, so that default settings are populated the first time I open a project on a new workstation?</p>
