Abstract event binding

Something like this should be added in 1.9:

$.widget.prototype._bind = function(elements, handlers) {
    if (!handlers) {
        handlers = elements;
        elements = this.element;
    }
    var self = this,
    $.each(handlers), function(event, handler) {
        elements.bind(event, function() {
          if (!self.options.disabled) { return fn.apply(self, arguments); }
        }
    });
}

In addition, track all events bound (at least those bind to something else then element) and unbind them in destroy.
