Add close and closed hooks for alert

Created by: jonathaningram

Basically, I have alerts in my app that are contained within a fixed layout - when closing the alert I need a hook so that I can remove a class from my fixed layout to "shift" it up by 30px or so to account for the space created when the alert is no longer there. FYI, the actual listener I use is this:

$(".alert-message").bind("closed", function() {
    if ($(this).hasClass("flash")) {
        $(".with-flashes").each(function(i, item) {
            $(item).removeClass("with-flashes");
        });
    }
});
