Support SSH from the get-go

[amirburbea]

I have a RPI that due to network restrictions, needs passwordless SSH connections as opposed to user/password.

It seems you want to generate the keys. If i can supply the dialog with a private mycert.id_rsa, can you just support that?

I think there's a workaround for now where I manually screw around with the config files but that's a pain.
