Wim 6a4ba6a689 Add support for authentication via ssh certificates and pub/privatekey (#442)
This adds support for authentication using a SSH certificate and normal public keys when you've got an ssh-agent running that has this certificate or your public key loaded.

First question when creating a new login is to ask about the ssh certificates or public keys, when the answer is yes, we don't need to ask about tokens/usernames anymore.
