Mirror.cs incorrectly sets attributes on open

In the mirror sample, around line 200 it has this:

if (mode == FileMode.CreateNew || mode == FileMode.Create) //Files are always created as Archive
                        attributes |= FileAttributes.Archive;
                    File.SetAttributes(filePath, attributes);

If you open an existing file with the readonly and/or archive bit set (eg open in Notepad), then attributes is Normal at the start of CreateFile and this line basically removes all attributes, clearing the readonly / archive flag on the file.

That looks good. Thanks for your help.
