* fmtowns: implemented hsync read from cff86, later 4th Unit games now boot
Similar to PR #2999, the later games in the 4th Unit series (zero, dagain, merrygor, wyatt) were getting stuck waiting for the HSYNC flag from 0xcff86 (bit 7). With this change they run past the initial menu.
(this is largely copied from Barry's implementation for port 0xfda0, so credit goes to him)
* fmtowns: replaced machine().first_screen() with m_screen
* remove no longer needed kov3 key from igs036crypt.cpp/.h
add kov2nl overseas set
rename ddpdojh -> ddpdojt because it's called 'Tamashii' also changed description to match format used by pgm1.cpp DDP titles.
updated some notes
* list Cave (nw)
* deleted 1 too many characters (nw)

According to the FM Towns Technical Databook, when reading from port 0xcff86, bit 4 should always be set and bit 2 is the VSYNC flag. With this change, Birdy Soft games (cal, myeyes, beast3...) boot instead of getting stuck in a loop waiting for the flag.
