DOMContentLoaded event is not fired

If I may, let me contribute to the ticket.

It appears that every events for the first element attached are never triggered.

In $w.addEventListener(), you set this.uuid to $events.length

w.addEventListener = function(type, fn){
  //$log("adding event listener " + type);

if ( !this.uuid ) {
    this.uuid = $events.length;
    $events[this.uuid] = {};
}
if ( !$events[this.uuid][type] ){
    $events[this.uuid][type] = [];
}
if ( $events[this.uuid][type].indexOf( fn ) < 0 ){
    $events[this.uuid][type].push( fn );
}

};

BUT, in $w.dispatchEvent() you check this.uuid like so:

    $debug("event target: " + event.target);

if ( event.type ) {
    if ( this.uuid &amp;&amp; $events[this.uuid][event.type] ) {</code>

Effectively, this first call to $w.addEventListener() will set the element'd uuid to 0, so $w.dispatchEvent() will never triger its events.

So it should be this.uuid = $events.length+1; in both $w.addEventListener() and $w.removeEventListener()

Well, I just had a little time to take a look at John Resig's original code to see were it got broken. It turns out that his code set the $events array (then simply events) with a first element, an empty object, as such:

var events = [{}];

Compare it to code in Thatcher's master branch (/src/window/event.js):

var $events = [],

Although never used, the first object in the events array of Resig's code made sure the check in dispatchEvent()

if ( this.uuid && events[this.uuid][event.type] ) {

never failed/evaluated to false, since this.uuid, set from events.length (now $events.length) for any new element, couldn't be zero.

Actually, initializing $events back to [{}] would be more elegant than using this.uuid = $events.length + 1; for both addEventListener() and removeEventListener(), as suggested is the previous ticket update (unless the change from Resig original code was done for a reason-I'm not familiar with envjs' history).

I don't have time to setup a github account, clone and submit a patch, so I'll leave it to you guys, hoping the extra details will help.
