Error when auto-generated config is used

[davidscholberg]

Goify appears to choke on the auto-generated config file with the following error output (happens with both help and auth subcommands):

Using config file: /home/dhscholb/.config/goify/config.yaml

Tested on 4ad9a78 (which is currently master).

Looks like this code is the culprit. It seems there is no default value set for the auth config variable, and as such if you're using the auto-generated config, the code will try to unmarshal an empty string.

The config code should be refactored to handle the auto-generated config file gracefully. I'll be closing this issue and handling the refactor in a separate one.
