title: app.config files of referenced dlls
body: <p>I have a Web Project (VS 2008) that references a bunch of DLLs. The DLLs are built separately, so the project references binaries and not DLL projects. 
  Some of the DLLs have their own app.config, which I want to be copied autmatically to the web project's output directory. 
  Is there any suitable <em>generic</em> way to achieve this?</p>
