title: CharacterType/ConfigurationType in vsprops
body: <p>I've been using Visual Studio's property sheets for building my code and I have a useful hierarchy of sheets controlling the build settings, rather than having them in the vcproj files.  This is great except for one thing.  I can't seem to set properties in the Project Defaults section such as CharacterType and ConfigurationType.</p>
  
  <p>I tried using a VCConfiguration tool in the vsprops but to no avail:</p>
  
  <pre><code>&lt;Tool
      Name="VCConfiguration"
      ConfigurationType="4"
  /&gt;
  </code></pre>
  
  <p>Can anyone tell me how this is accomplished please?</p>
