Default colour as foreground colour

In the default colour setup (white on black), white could only
with great difficulty be used as customized foreground colour,
because the colour pair COLR_CUSTOM then was identical to
COLR_DEFAULT (default on default). This made it impossible to
distinguish the selected element in lists.

The patch turns on the video attribute bold when default is chosen
as foreground colour.
