title: A way to clean up Nuget packages in the csproj file?
body: <p>As I add and remove references sometimes I don't always "uninstall" a package which appears like a reference.  So it remains "installed" in the Nuget package explorer.  It seem like I could really use something that cleans up the .csproj and the packages.config file -- is there something that does this?</p>
  
  <p>This would be useful for both Visual Studio (VS) 2010 and VS 2012.</p>
