backupninja's duplicity handler does not pass ssh options correctly for current versions of duplicity

[Jeffery von Ronne]

The duplicity handler in backupninja does not pass any "sshoptions" given in dup action configuration files to duplicity correctly.
This can render backupninja's duplicity support unusable if ssh options are required to log in on the server on which the backup is to be stored. The reason for this is that duplicity changed the way it accepts ssh options. The version of duplicity in precise (0.6.18) has an --ssh-options option for this. In older versions, one could tack it on them on the end of --scp-command and --sftp-command options. This no longer works and produces the following error:

  Info: Warning: Option --scp-command is deprecated and ignored. Use --ssh-options instead.
  Info: Warning: Option --sftp-command is deprecated and ignored. Use --ssh-options instead.

The code in question is on line 110 and following in /usr/share/backupninja/dup.
