This patch adds the EventTarget class and makes Node inherit from it. You can register event listeners on an EventTarget, and when you call dispatch_event() on it, the event listeners will get invoked. An event listener is basically a wrapper around a JS::Function*. This is pretty far from how DOM events should eventually work, but it's a place to start and we'll build more on top of this. :^)
