Separate Ckeditor 4 in a submodule

I detached the CKeditor 4 functionality from the Augmentor module and I moved everything into a new submodule. Also I added an update_N hook to install this new augmentor_ckeditor4 submodule to don't breack sites using it.

I've installed the issue fork and tested it to verify that Augmentor is able to work without requiring CKeditor 4 being invoked on the entity edit form. It works as expected both if there is no CKEditor at all on the form or if CKeditor 5 is enabled instead.

I've also made a couple of commits to this issue fork.

I moved the hook_update_N function into an *.install file in accordance to typical Drupal best practices.
I made enabling the augmentor_ckeditor4 module dependent upon having CKeditor 4 already installed to prevent users who do not want CKeditor 4 getting it enabled by accident.

And requesting a review of my commit to change the hook_update_N processing.

Thanks @hyperlinked, tested and merged.

Why are we keeping the obsolete files after moving?

Thanks Naveen.
