* event objects have isDefaultPrevented, isPropagationStopped and isImmediatePropagationStopped methods. * Removed donative and dohandlers from $.trigger * event.result carries the last returned data from a handler(not undefined). * $.trigger doesn't keep bubbling if stopPropagation() is called. * Same event object is used all along for global trigger * Fixed the bug where target doesn't change when triggering on many elements. * The data array on $.trigger was accumulating objects as it bubbles. testrunner: adding more tests
