Support for Quotes and Spoiler

[Andre601]

I've created a TXT file to quickly check what this site actually renders and what not.

From this test does it look like that it currently doesn't render Quotes and Spoilers.
While Spoilers are a Discord thing, quote more often than not is a part of default markdown, which makes it really odd, that it isn't a part of the markdown js used here.

Perhaps it's also caused by some weird handling in the custom.js?

One thing I noticed is, that the Copyright C at the bottom is rendered differently when viewing a page than the default page, which I assume is caued by the renderer parsing the unicode using Tweemoji, when viewing a file, so perhaps this should be improved too.

And as a final note, would it be difficult to implement syntax highlighting? I can imagine it being somewhat tough to do, but it could be beneficial to have here.

Markdown formatting is handled by simple markdown; using an updated version may rectify the lack of quotes and spoilers.

The copyright icon is indeed being affected by twemoji (https://github.com/DiscordWebsite/Txt/blob/master/js/custom.js#L54), and this could likely be fixed by parsing only a subset of the page instead of the entire body.

By syntax highlighting, I'm assuming you mean in codeblocks? If so, https://highlightjs.org/ may be a good place to start, as I believe Discord uses a modified version of it.

Looks like the site broke all of a sudden. Perhaps Discord has recently changed stuff breaking it?
