Adapts juggernaut prototype code to extjs.

Example usage:

var jg = new Ext.Juggernaut(
   {
                                "session_id": 000, 
                "flash_color": "#fff", "height": "0px", 
                "swf_name": "juggernaut_flash", 
                "bridge_name": "juggernaut", 
                "swf_address": "url_2_jug/juggernaut.swf", 
                "width": "0px", "reconnect_attempts": 3, 
                "ei_swf_address": "url_2_exp/expressinstall.swf", 
                "host": "127.0.0.1", 
                "debug": true, 
                "reconnect_intervals": 3, 
                "flash_version": 8, 
                "port": 5001,
                "startup":"manual",
                })

jg.addListener("juggernaut:connected",function(){
                        Ext.log("i am connected!")
                    }); 
                            jg.addListener("juggernaut:msg_received",function(data){
                                           Ext.log ("Received " + data.WHATEVERYOUSENTASJSONINTHEBODY);
                                         })Note that I added a new parameter "startup" which indicates whether Juggernaut flash object should be created on window.load ( startup:"auto" ) or if it should startup when the Ext Object gets created (startup:"manual").
