SSH-command : set-account

Added a new command, 'set-account', that can be used to edit
various settings of an account, such as active status,
emails, ssh keys and the full name.

The commandline pattern:
set-account [--full-name <FULLNAME>] [--active|--inactive]
            [--add-email <EMAIL>] [--delete-email <EMAIL> | ALL]
            [--add-ssh-key - | <KEY>]
            [--delete-ssh-key - | <KEY> | ALL] <USER>
