Make sure hugo --version prints the version and does *nothing* else.

Any program, when asks to print their version, only prints that, and then
stops.
hugo checks the config (and prints a warning message if not found), and
proceeds to generate the site!
Yet, the user just wanted to check the version.

This patch makes sure hugo stops after printing the version.
