Add colorized output for ls subcommand
Initiative is turning into a little hackathon. Trying to beautify ls output a little since the number of configured containers on my main server is growing to a large number (currently 44). text/tabwriter can't handle SGR codes correctly. Investigations led me to the "ansiterm" library. I'm not crazy about the API really, but it handles all the corners I'm concerned about.
