Rewrite menuaim as a stateful widget?

[robfe]

Hi, i've had situations where I want to programmatically set/get the selected row. With the current architecture this doesn't quite work. I'd be happy to rewrite menuaim as a jquery widget (http://learn.jquery.com/plugins/stateful-plugins-with-widget-factory/) - let me know if you'd take a PR?

One disadvantage that I can think of is that there would be a new dependency on jQuery.widget...

#41 is a step towards this that doesn't depend upon jQuery.widget
