Feature: selective export of layouts

[Drarok]

This will undoubtedly need me to do some tidying-up to match the current standards, but I figured it was worthwhile as a starting point to make this as a PR so we can discuss it.

Instead of exporting everything into one big file, we wanted to select individual models to export the layouts of, which is what this aims to do.

Hey @Drarok thanks for the PR this is a great idea, I love it!

In terms of controllers/API - is there anything that comes to mind that is missing/could be added before this is merged?

Also could you please elaborate on the "current standards" parts, what did you mean by that?

Thanks again for the PR, this is an awesome idea!

I had to guess a lot, such as how to fetch the available content types, but mainly I wasn't sure if I was following coding standards or anything like that. It's functional but not pretty! 🙂

@Drarok ahh understood! : ) Thank you for giving this a thought and for this feedback.

I'm planning on adding some more contributor guides and description of existing codebase in near future. But definitely could use some help there, haha.

With that said, I'll give this a test later tonight and will aim to merge asap, I like the idea of this feature a lot!

Hey @Drarok , sorry for the delay, I have just release 3.5.30 with updated routes and some cleanups.

Could you please tweak your PR to be up to date with that? Many thanks and I will take a look ASAP to merge
