Sort of sshd_config.erb should be removed.

Port must be specified before ListenAddress as indicated at http://www.openbsd.org/cgi-bin/man.cgi?query=sshd_config&sektion=5. Otherwise you'll have the following error from sshd daemon

```
/usr/sbin/sshd -d
/etc/ssh/sshd_config line 33: ports must be specified before ListenAddress.
```

Second change fixes HostKey issue. Again it's described at http://www.openbsd.org/cgi-bin/man.cgi?query=sshd_config&sektion=5
