Description
Currently even if I specify
```go
server := &ssh.Server{
Addr: "0.0.0.0:2222"
}
```
Server will listen at both `ipv4` and `ipv6`. Because line [server.go#L330](https://github.com/gliderlabs/ssh/blob/master/server.go#L330) has protocol `tcp`.
It would be nice to have an option to set `tcp4` instead.
