解决TableView / ScrollView上的Menu问题
1划出区域还可点击
重写CCMenu的触摸事件函数 TouchBegin/TouchMove/TouchCancle/TouchEnd
如果点击超出了 TableView/ScrollView边界则 TouchBegin返回false
2导致View不能滑动
透传CCMenu的触摸吞噬、让触摸可以下传，然后再touchMove中增加一个触摸滑动校验、如果触摸移动大于某个值（比如16），那么CCMenu则丢弃该触摸、不让menuItem执行activate，那么滑动的时候view上的menu就不会响应了。
也可以自己写个新的view，把里面的menu换成sprite，自己判断点击的位置，然后就知道点击的是哪一个了。相比之下重写menu工作量小多了、、、
