Move public files into a subdirectory

Fixes #1684

@alextselegidis, this is version 1 of the PR. Please let me know if you want any changes to it.

The result looks even better when CodeIgniter is under vendor (I implore you to at least have a look at #1680!): in combination with that change, the app is cleanly split into three very distinct directories: public/ holds the index script and public files, application holds private PHP files which belong to this app, and vendor/ contains third-party code.

In another CI3 project, I additionally renamed application to app, as is done in CI4, but that's not necessary.

Version 2 is very much simplified, but also improved. I moved git-tracked assets back to their original place, but modified the gulpfile to generate their production versions (and copy images) to public/assets. This way, the diff is much smaller, and there's much clearer separation between source and production assets. I also undid irrelevant docker-compose.yml changes. The diff now only affects four files and npx gulp build generates a zip which seems what I would expect.

Hello!

Thanks for this PR.

The application restructuring is done step by step with each major release, so it can be that this change is delayed until merged.

I will leave this PR open for now until the time for the assets move comes.
