测试通过ie7、firefox 24、chrome 32.0.1700.6 Aura

1.播放声音ie使用EMBED标签、其他使用html5的audio标签

2.桌面通知chrome虽然实现了Notification 但似乎没有效果，并且使用Notification.requestPermission会导致浏览器崩溃，所以只能使用自家的webkitNotifications，另外需注意的是webkitNotifications.requestPermission()需要手动触发

 

document.onclick=function(){message.noticeinit()};

firefox实现桌面通知就比较简单了，参照html5 的桌面通知就行了

3.ie可以使用vbscript 的msgbox模拟桌面通知,因为msgbox会是系统重新对焦在ie浏览器上
