Most of this change is a conversion of the old FileDetails struct into a new LocalFileDetails class. The new class keeps the members private, and keeps the Unicode and MOR representations of the string separate. The NuFX and DiskImg libraries don't support UTF-16 filenames, so we stil can't add files with non-CP-1252 filenames, but we're a step closer. Also, update NufxLib with a couple of fixes from the main project. Also, fix handling of "%00" when adding files. Also, mark most of the A2FileDOS fields private. Not sure why they weren't.
