Add --black for terminals incapable of use_default_colors

Browse Source 
See the discussion in #18.

Use --black option to use black background regardless of the default
background color of the terminal. Also, this option can be used to fix
rendering issues on terminals that don't support use_default_colors (man
3 default_colors). Depending on the terminal, use_default_colors may or
may not succeed, but the Ruby version of it always returns nil, it's
currently not possible to automatically enable this option.
