Added close_connection

This lets you close the connection to redis

Is this ok?

How do I close the connection? I have tried calling close_connection on EventMachine::Hiredis::Client with no success.

Here is my code:

require 'rubygems'
require 'eventmachine'
require 'em-websocket'
require 'em-hiredis'

EM.epoll
EM::Hiredis.logger
puts "Total descriptors: #{EM.set_descriptor_table_size(10230)}"

EM.run do
  socket = EM::WebSocket.start(:host => "0.0.0.0", :port => "8080") do |ws|
    ws.onopen do
      @subscriber = EM::Hiredis.connect('redis://127.0.0.1:6379/0')
      @publisher = EM::Hiredis.connect('redis://127.0.0.1:6379/0')
    end

    ws.onclose do
      puts "Websocket: closed"

      @publisher.close_connection
      @subscriber.close_connection
    end
  end
end

After onclose I get "Websocket: closed" printed on screen but when looking at redis-server log the two connections remains open.

Ok, my fault. I forgot to add require 'bundler/setup so the wrong version was being load.

Great gem.
