[更新]键位设置组件和连招组件[KeyMapper & ComboInput]

解决了有时不能更改按钮名的bug。Flash的类型转换的问题。
更改了使用的方法，现在不需要在场景中添加km和ci的组件了，只需在库中保留km_ci组件，然后在代码中new出KeyMapper或者ComboInput的对象即可。

there are some global value for buttons state

you can use these value to determine the button states:
KD:key just pressed down
KU:key just released up
KH:key is holding down
KR:key is free
