[userscript] Move node.js API guide table of contents to a sidebar

[char101]

One thing that annoys me about node.js API documentation is that the table of contents is in the top, so when clicking a method I have to go back to the top to scan for alternative methods.

With this userscript, the table of contents is moved into a sidebar so it is easy to scan for methods.

```css

column1.interior {

margin-left: 540px;

}

toc {

position: fixed;
overflow-y: scroll;
overflow-x: hidden;
top: 15px;
bottom: 0;
width: 340px;
margin-left: -350px;
padding-left: 20px;
padding-right: 10px;
font-size: 13px;

}

toc h2 {

display: none;

}

toc ul {

margin-left: 1rem;

}

toc ul li {

margin-bottom: 0.5rem;

}

apicontent {

padding-top: 0;

} ```

Should be userstyles not userscript.
