调整旧式网页（指那些几乎没有排版，直接用 <h1>、<p> 等等标签从上到下堆下来的网页）的排版，将内容宽度限制为适合阅读的宽度，添加目录侧栏，点击可以跳转到对应位置。此脚本不影响“现代化的”网页（至少我写的时候是这么想的，如果有误伤，可以到 github 上告诉我）。

// @description Limit the width of old-styled websites (which has it's text content expand across the whole wide window.GoodForReading) and add a catalogue sidebar for a comfortble reading. This script does not affect those "modern" web pages (At least I tried to avoid that. If it fails, you can report the bug on github).
