Michael Meyer f5e3bc3d96 Remove gendered mons indices from roles, races
There are no longer distinct gendered versions of monsters, so femalenum
is unused (i.e. set to NON_PM) for all roles and races. Take a pass at
removing all uses of/references to femalenum, and rename 'malenum' to
'mnum' since it no longer has any particular association with
gender or sex.
