Better TinyMCE code editor

[MarskyMessier]

I feel like the current code editor on core is really lackluster to say the least, and messes up a lot of things (doesn't retain any stylization whatsoever, changes when going back to WYSIWYG etc.), I think Moif's extension http://wiki.lorekeeper.me/index.php?title=Extensions:TinyMCE_Code_Editor is a huge QoL upgrade on what we have already, and is small enough not to disrupt anything in core (and wouldn't break anything so I assume it could be merged in dev without issues, or with just minor tweaks?).

Would require @AW0005's permission, but I have a feeling it wouldn't be too hard to get..

Yea I don't mind at all

Could this issue be closed or does the ext need more work on it?

It's fine. Itinerare linked the PR, so it'll close automatically once it hits main branch. :)
