curses: hilite_pet, hilite_pile without color

The curses interface was ignoring video attributes (bold, inverse, &c)
when color is toggled off or if built with TEXTCOLOR disabled.  Honor
attributes regardless of whether color is displayed.

Also, toggling 'hilite_pet' On during play wouldn't do anything if the
curses-specific 'petattr' option had been left as None.  (It worked as
intended if set in starting options.)
