Get JID and Service info when Strophe attaches a session

[WasserX]

The function onStatus of the pubsub plugin sets the JID and Service vars needed for executing actions when Strophe sends an status of CONNECTED.

If the user is reattaching / attaching to an existing session, those variables are not initialized.

This commit makes it possible to update those variables when Strophe reports the status ATTACHED.

Hi

Do you use this for BOSH prebinding? Do you mind sharing additional bits of code? Example usage would be great.

So, I use sessionStorage and my objective is that if you reload the page, you do not start a new connection, so the code is more or less like this:

this.conn = new Strophe.Connection(this.options.gateway.bosh.endpoint); //Snippets of code for understanding

if(!force && typeof sessionStorage.getItem('JID') === 'string'){
                    sessionStorage.setItem('RID', parseInt(sessionStorage.getItem('RID'))+1);
                    this.conn.attach(
                        sessionStorage.getItem('JID'),
                        sessionStorage.getItem('SID'),
                        sessionStorage.getItem('RID'),
                        this.onStatus.bind(this),
                        null, null, null)
                } else{
                    this.conn.connect(
                        this.options.username,
                        this.options.password,
                        this.onStatus.bind(this),
                        null, null, null);
                }

The function onStatus is called whenever the status changes.

When we do an attach, onStatus receives Strophe.Status.ATTACHED but it will never receive Strophe.Status.CONNECTED, but once we receive ATTACHED, we start receiving all new published events.

So, once I receive an Strophe.Status.ATTACHED I assume I was in the same state as before.

The problem is that once i'm reattached and I try to do a 'subscribe' op, the JID inside strophe.pubsub because they are filled from strophe when strophe sends a status of Strophe.Status.CONNECTED
