headings in option menus

There was a great deal of inconsistency in
different menus on how headings were displayed.
This allows the user to select what they like best.
I was motivated to do this, because I wasn't satisfied
with the appearance of ATR_INVERSE in the menus
on win32tty, and several of them specified it.
