調整舊式網頁（指那些幾乎沒有排版，直接用 <h1>、<p> 等等標簽從上到下堆下來的網頁）的排版，將内容寬度限制為適合閲讀的寬度，添加目錄側欄，點擊可以跳轉到對應位置。此脚本不影響“現代化的”網頁（至少我寫的時候是這麽想的，如果有誤傷，可以到 github 上告訴我）。

// @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).
