微信读书阅读样式优化

常在电脑和手机上阅读，需要多端同步功能，目前仅发现微信读书是免费同步的，但是网页版的样式不符合自己的阅读习惯，于是通过油猴脚本定制自己喜欢的阅读样式。

功能介绍：

1、宽屏显示，设置满屏、80%和默认3种宽度模式，浮动菜单、字号控制条随模式变换位置
2、页脚优化，调整“下一章”位置，设置按钮隐藏、显示和默认3种模式
3、显示、隐藏滚动条
4、更改浅色模式背景颜色，共有豆沙绿、杏仁黄、秋叶褐、胭脂红、海天蓝、葛巾紫、极光灰、青草绿、银河白9种可选
5、沉浸式阅读：导航栏、浮动菜单顶部显示，下滑隐藏
用户配置保存在油猴脚本存储区，下次打开网页直接读取。
没有设置阅读界面按钮，而是通过油猴菜单，是为了更沉浸于阅读。
