Cobra, the CLI commander in use in Hugo, has some long awaited improvements in the error handling department. This enables a more centralized error handling approach. This commit introduces that by changing all the command funcs to `RunE`: * The core part of the error logging, usage logging and `os.Exit(-1)` is now performed in one place and that one place only. * The usage text is now only shown on invalid arguments etc. (user errors) Fixes #1502
