Turn off auto-code input

[hill]

Hi Tim - this is such a cool project!

The auto-code input thing is a really awesome idea - but it would be really cool if there was an option to turn it off and write into the editor yourself as you read. When I read through tutorials I like to type it up myself so I actually have an idea of whats going on, rather than copy and paste.

By the looks of this:

BAD CODE ALERT!
 **  - This is the original conceptual version of tutorial markdown
 **  Im currently doing a full rewrite, now I understand the ideas,
 **  needs, goals and aims of the project.
 **  * There is some nasty stuff in here! *

you look like you're going to be rewriting tutorialManager.js.

I'd love to implement this after the rewrite or you can add it in as you're rewriting.

Again, really excited to see where this goes 😄
