Title: get remote-host's IP Address

I've made a pull-request for issue #103
I'm wondering if you like this.

```ruby
EM::run do

EM::WebSocket.start(:host => "0.0.0.0", :port => PORT) do |ws|
ws.onopen{|handshake, connection|
puts "connect from #{connection.remote_addr}" ## => "127.0.0.1"
end
end

end
```
