Improve setup-server

Browse Source 
The order of parameters is now changed to make it easier when deploying
to a lot of servers.

Also, it introduces the concept of a friendly name, which is useful when
DNS is not available for a specific host. Instead of being forced to
have the alias be the same as the IP address, it can now be named.
