Add title to "add" & "autoadd" commands

[deftdawg]

I have a scenario where I parse a config ini file and then generate calls to goss. It would be helpful if there was a way to invoke goss and have the title written to the goss.yaml file in a way similar to this:

./goss -g online.yaml a --title 'Service.ini: ldap service address for Server' addr ldap:389

This seems like a nice to have, but lower priority.

Approved.
