SwipeBackHelper 关于RelateSlider平滑度的建议与修改，望作者重视

首先非常感谢作者的这个开源库，网上很多swipeback的开源库，但是你这个和其他最大的区别就是有微信联动效果，曾经我想实现微信联动效果，始终没有实现，最终在网上找到了你的这个开源库，顺利的解决了我的需求。但是在使用这个库的时候发现存在很多问题，最明显的一个是statusbar闪烁问题，看到别人也有提到这个问题，另一个就是开启微信联动功能会导致卡顿，特别是滑动松手后上一级activity会一顿一顿地，经过多版迭代后始终没有得以解决，然后我就认真研究了你的这个开源库，目前算是找到了一些优化方案，我想有必要通知你，更加完善这个开源库。问题1：statusbar闪烁问题，这个是由于该库插入的layout并不能覆盖到statusbar，这是因为statusbar比较特殊，所以需要去掉系统的statusbar自己重绘。问题2：RelateSlider联动卡顿问题，需要把RelateSlider里面的setX（）函数换成setScrollX（）函数，就会得到明显的改善。问题3：如果在activity已经加载完成后再进行setSwipeEnable就会造成某些View如Switch的isLaidOut()函数始终为false，导致动画丢失。具体修改方案我会贴出代码。问题4：新版本代码有问题，如果把setSwipeEnable设置为false以及禁止联动，就会导致背景透明，我看到也有人提到这个问题，原版是没有问题的，是因为新版额onPostCreate里面发生变化。改回原版就没问题。

以下是代码，希望作者能够关注和参考，大家一起完善这个开源库，让更多的人能够正常使用。
