Support code syntax highlighting

[krukow]

Proposal to use highlight.js: https://highlightjs.org/

would enable things like

function log_generator () {
   return function {} {console.log("You've got it");}
}

class A
{
    public void Bar() 
    {
        Console.WriteLine("You've got it");
    }
}

class A
    def foo(arg)
        "You've got it, #{arg}"
    end
end

(defn foo [] (println "You've got it"))
