The name of the bootloader is syslinux, while isolinux is just one of many components. isolinux.bin now also accepts syslinux.cfg as a configuration file name (as do all other loaders). Thus, rename the isolinux/ folder to syslinux/, and rename isolinux.cfg to syslinux.cfg. The only occurrence of 'isolinux' is now the actual loader file 'isolinux.bin'. This makes the transition from isolinux to the other syslinux loaders easier when remastering the ISO onto another medium.
