`ckan.exe show` - Don't die on null authors.

Apparently authors are optional according to the CKAN spec. I didn't

I have some mods installed with null authors when I think they really
should have an author, and while there's almost certainly a bug there,
it's a *different* bug to this.

Hand tested. Closes #673.
