Function choose_classes_menu

src/windows.c:1643–1761

* This is a somewhat generic menu for taking a list of NetHack style * class choices and presenting them via a description * rather than the traditional NetHack characters. * (Benefits users whose first exposure to NetHack is via tiles). * * prompt * The title at the top of the menu. * * category: 0 = monster class * 1 = object class * * way * FALSE = PIC

 * Returns number selected.
