Add callbacks to javascript page parts adding/selecting functions

[seancribbs]

Something like this:

var TabControl = Class.create({ [skipped]

select: function(tab) { [skipped]

this.select_callback(tab.label);

},

select_callback: function(pagename){}, });

Ed. IMO it would be better to fire custom events. Like tab.fire("tab:selected") or something. Then you can just observe.
