The wizard-mode option to highlight female monsters stopped having any
in-game effect after cb0c21e. Formerly it caused female monsters to be
highlighted with a red background (red color + inverse); this commit
uses inverse video only without overriding their color. Ensuring the
color override works consistently with the ENHANCED_SYMBOLS 24-bit color
doesn't seem worth it for what is a very niche debugging option, and I
think inverse video should probably suffice.
It also used to be a TTY-only option, but this enables it in curses as
well.
