Much simplified the Wave "decoder". It will now use the MUtilities library to copy the file, rather than SHFileOperation(). For whatever reason, copying a file to a directory via SHFileOperation() prevents that directory from being deleted later. But only when trying to delete that directory from the same process where SHFileOperation() had been called. It can be deleted, e.g., in Windows Explorer just fine - even when the process that called SHFileOperation() is still running. Anyway, we simply avoid SHFileOperation() now.
