title: Is there a solution-wide way to Untabify the whole files
body: <p>I have downloaded a project and it is all using Tab , but I always use Space. There is the option that "Edit->Advanced->Untabify"   but for then I have to select files one by one and do this for all of them, so I was wondering if there a way that I can apply thzt to the whole files in the project. I am using C# and VS2010 Pro.
  I also have Resharper installed, in case it has something that can help. </p>
