Colorize set-user-ID and set-group-ID files and sticky,

other-writable, and sticky-and-other-writable directories.

(indicator_no[]): Add new symbols.
(indicator_name[]): Add corresponding mode strings.
(color_indicator[]): Add an entry for each new mode string.
(print_color_indicator): Honor new types.

From Mike Frysinger, based on a patch from Fedora.
