目前发现两个bug。
CCToggle这个类 设置了两个静态变量控制事件发射，结果两个逻辑不同的地方，用了相同的判断!_triggerEventInScript_check&&triggerEventInScript_ischecked，导致check事件和uncheck事件不能正确触发
刚才又被我发现AnimationState这个类里面又乱加判断_target&&_target.isValid导致编辑器上定义的clip产生的AnimationState的注册事件不能触发。因为这种AnimationState没有_target这个私有变量，
唉╮(╯▽╰)╭
你在 chrome 里面看 cc.toggle.js 的代码， 其实那两个静态变量根本就没有， deleted-branch-v2.2.2-release 这个 tag，才是编辑器内置引擎用到的代码分支

希望能修复 bug， 出个 2.2.3
