Resets the 64 bit OutputDirectory settings in the .vcproj files for
OpenSceneGraph and OpenThreads to be the same as the Win32
settings.  This is a workaround for Visual Studio's annoying practice of
generating this setting itself when creating the 64 bit configuration,
rather than reusing the Win32 setting.

To run, open a shell and execute
        perl $file

options:
  -h, --help               print help information
";
