Clarified and added to mame.lst 4 rom sets which were mistakenly missing but had rom_start and game( macros set up.  These include: fcocku2_4c, fcockt2_4e, pex2029p and jngld_l1. In other cases of unused rom sets - I reverted to #if'ing the whole section while consolidating and deleting entries, if possible. (nw)
