[magnifier] add option for which elements to magnify

[scott.gonzalez]

Allow setup like this:

HTML:

<div id="nav">
    <a href="1.htm"><img src="1.png" /></a>
    <a href="2.htm"><img src="2.png" /></a>
    <a href="2.htm"><img src="3.png" /></a>
</div>

JavaScript:

$('#nav').magnifier({
    elements: 'img'
});
