Skip children that aren't Nodes, strings, or numbers

[fregante]

ReactDOM.render(
	<div>
		<p>My name is {'John'}</p>
		<p>My name is {1}</p>
		<p>My name is {<i>a Node</i>}</p>
		<p>My name is {<>a DocumentFragment</>}</p>
		<p>My name is {NaN /* rendered because typeof NaN === 'number' */}</p> 

		<p>My name is {false}</p>
		<p>My name is {true}</p>
		<p>My name is {null}</p>
		<p>My name is {undefined}</p>
	</div>,
	document.body
);

Currently dom-chef specifically tests to render falsey values as strings, but I think we should match React's behavior here.
