Add more trusted networks

[bitboxer]

It would be great to be able to add more trusted networks. E.g. the wlan at my girlfriend, my parents etc...

something like:

sheepsafe list sheepsafe add

would be great.

Sure, good idea to add a command line UI for that. Until then, to add more, you can open ~/.sheepsafe.yml in a text editor and add them like so:

  trusted_names: 
  - myplace_lan
  - girlfriend_lan
  - parents_lan
