'color' in simple options menu

'color' appears in the simplified O menu for curses, but was not
showing up for tty.  That's because it is hidden when tiles are in
use, and tty has had a bogus value for iflags.wc_tiled_map.

Presence of USE_TILES is not a reliable way to tell whether tiles
are available in a multi-interface binary.  Nor is the setting of
DEFAULT_WC_TILED_MAP from config.h.
