Change flow in CKEditor modal dialog, separate submit buttons.

First version was created and all plugins were updated.

It looks like this:

However, this might be a breaking change, because all existing plugins would have to be updated.

The MR is in draft: it would be good to remove that if you have finished with it, regardless of the maintainers decision about whether it can be merged yet.

Applies cleanly, works well for meL: I *much* prefer this flow which makes a lot more sense than the current one.

Thank you Dale :-)
Draft removed.

Then we'll say RTBC :)

a.dmitriiev → made their first commit to this issue’s fork.

I have refactored a bit the MR and all the plugins, so that they use the base class more, as most of the plugins use the same form elements, so it was easy to generalize the behavior.

Change still works, but the new code changes make the code itself a lot neater. I think this is a better version than the original: setting back to RTBC

Looks good, getting merged!
