Progressbar callback at the end

Hi.

I changed to use the ui progressbar, but noticed that it didn't have a callback for the event at the end of the bar. I needed that for my project.

I did a hack to do that like this:

Added the following line animate methods complete callback (around line 70)

''

self.end();

''

Also I added the method after the text method (around line 178)

''

end: function(){

this._propagate('end', this.ui());

},

''

Now you can call the progressbar like this:

''

$("#progressbar").progressbar({end: doMyThingAtTheendMethod});

''

Could something like this added to the plugin?
