Defect 10. AlphaFS 2.2 copies a folder only into an existing destination
folder; otherwise DirectoryInfo.CopyTo fails with a
DirectoryNotFoundException for the first file, so Copy-Item2 could not
copy a folder that contained files. The cmdlet now creates the
destination folder first; AlphaFS then copies the files and subfolders.
Tests/ItemCmdlets.Tests.ps1: 1 test.
