JsSIP.UA connected event enhancements

[pontello]

Lets suppose that I have user agent with option register=false

var uac = new JsSIP.UA({ register : false});

In my understand, if connected event is fired, I am able register, for example:

uac.once('connected', function(e){
    uac.register();
});

But unfortunately it is crashing inside following method ( this.registrator is NULL):

UA.prototype.register = function(options) {
  this.configuration.register = true;
  this.registrator.register(options);
};

It crashes because not all internal variables are initialized. I have to do something like following code to make it work:

uac.once('connected', function(e){
    setTimeout(function(){
        uac.register();
    }, 0);
});

My suggestion is to change internal implementation to allow us to register after connected without use timeout hacks...

Indeed a bug. Not sure if this happens in more places. A solution would be to make all the events to fire their code within a setTimeout(function(){ XXX }, 0).

@ibc, you are very right. And I remember you already suggested me so. I've applied such change in the event emitter for the #163 issue patch.

Thank you
