// jQuery extension to bind events that depend on an AJAX request.
//
// As soon as the event is bound it will start preloading the data from the server.
// If the event occurs while the data is still loading, your callback will be called
// as soon as the data finishes loading.
//
// Example:
//    $('a.more').bindWithPreload('click', '/foo.json', function(data) {
//      alert(data.message);
//    });
