title: Nuget Clean Package Remove/Install
body: <p>I'd like to remove an entire nuget package, and cleanly install it in my project again.</p>
  
  <p>Sadly, for some reason it skips removing files that have been "modified", and then skips putting them in the project on reinstall, because they already exist.</p>
  
  <p>Is there any flag i can set to unconditionally remove every single trace of a nuget package, alternatively overwrite all existing files?</p>
  
  <p>Thanks.</p>
