allow to change the logging style; introduce some new ones

titan: parse the response code and exit accordingly
Exit with 0 if the response code was in the 2x or 3x range, or with 2 for other codes. It already exits with 1 upon any other error (including parsing errors.) Print the redirect code on 3x to stdout and the meta to stderr for the 1x, 4x, 5x and 6x ranges.
