- renamed workingDirectory into workingDirectoryPath - added FSDiskFileSystem class>>workingDirectory
- renamed working into workingDirectory. - deprecate working - better printOn: for DirectoryEntry - comments allChildren, allFiles, allDirectories, children, files, directories, childDirectories, childDirectories. Since childDirectories is the same as directories and childFiles the same as files may be we should deprecate child* because this is not good to have both. Stef
