deliteful/Toaster widget

I misspoke in my comment above.   Currently placeAt() has this code:

	// Start this iff it has a parent widget that's already started.
	// TODO: for 2.0 maybe it should also start the widget when this.getParent() returns null??
	if (!this._started && (this.getParent() || {})._started) {
		this.startup();
	}

As you can see, I want placeAt() to call startup() all the time, but it isn't yet.   So, for the time being you need to call it yourself.
