- 使用onPageStart与onPageEnd都替换为onPVStart，onPVEnd

- 优化onPageStart，让其真正有用
- PV参数使用协议，这样view也可以使用这些PV属性。例子：GMWelfarePopView
- selectedNavigationController的安全性，已经优化为visibleController
- 优化了referer的获取
- netStatus获取优化
- GMPhobosPV 优化
- GPS优化
- 精简了handlePVEventAppInForeground、handlePVEventAppInBackgound
- onPVStart真正变得有用途
- 添加catchNullInAttributes
