MAJOR: Implement POSIX permissions (rwxrwxrwx) / DOS attributes (hidden/readonly/archive/system), detect symlink target changes and permissions/attribute changes in 'status' operation (FileVersionHelper), set permissions in FileSystemAction.createFile(), add DOS/POSIX stuff to XML DAO, implement ugly workaround for 'download multichunks for rename file system actions' issue; MINOR: TestClient.getLocalFiles() skips locked files (leads to issues in tests, still unresolves -- not sync issues)
