Fun feature: Allow embedded text files as either plain text or highlighted code

[halfwit]

These additional views allow embedding of text uploads from the site. They can be used as follows:

text{upload/myhash.txt}
code{upload/myhash.txt}

Internally, the code element uses highlight.js, which is fetched on demand from cloudflare for higher locality, likeliness of cached status, and ease of maintenance.
The text block is simply a <pre><code> element, ensuring that everything is html escaped.

Before this is accepted, there is a possibility that we could add styling to the code blocks, since highlight.js facilitates that pretty trivially - we could do code{upload/myhash.txt, stackoverflow-dark} as an example.

The code change would look something like this:

case "code":
    $Args = explode(",", $content);
    $Code = file_get_contents($Args[0]); // will always run
    $Code = htmlspecialchars($Code);
    if ($Args[1])
        $Style = $Args[1];
    else
        $Style = "default";
    return "<link rel=\"stylesheet\" href=\"//cdnjs.cloudflare.com/ajax/libs/highlight.js/10.5.0/styles/$style.min.css\">
    // [...]

Which would let you do something like,
code{upload/myhash.txt,stackoverflow-dark}

It's kinda neat, again just a fun feature.

Ideally we should be loading these dependencies via npm so we can self host them instead of using a 3rd party.

npm dependencies are currently defined here -
https://github.com/wetfish/classic/blob/master/wiki/src/package.json

and there are symlinks to the node_modules folder
