(mess) pc: fix font for asst128 (nw)

asst128_dsk: add support for asst128 ssqd 360K disks (nw)
--
Added a new format class for asst128 floppies because the 360K SSQD disk format conflicts with the standard 360K DSDD type.  The Assistant 128 BIOS translates disk commands so 360K DSDD disks boot fine though.
