issue with core/assets/vendor/ckeditor/ckeditor.js

One of the big issues with this file specifically is that it loads many many other files, not just javascript either. There will be no way to make this work without a considerable effort. I think the best way forward is to create an editable exclusion list. Those files on the exclusion list will not even be shown to the user when they open the 'Manage Javascript Files' page and the minified version will not be swapped out (in case the exclusion was added after the minification was done).

This will require the addition of a configuration form to handle the textarea that will contain the exclusion list. Need to add a separate settings page, under the Development section.
