ncurses color fixes (#1482)

Browse Source 
* specials: avoid duplicating color specials when both ncurses and a graphical output are enabled

* ncurses: fix black

we previously used the ncurses color as the id for its color pair, but this scheme needs to be shifted by one to avoid using the invalid 0 color-pair id for black (color id 0)
