Update CKEditor library to 4.6.2

Patch updates can be done in patch releases, so no need to do anything special here.

4.6 is in 8.3. 8.2 will never get 4.6.2.

I would like to help in updating.

IS updated.

@boaloysius: you're welcome to do so! There's plenty of examples to look at for updates we did in the past, see the updated IS :)

Should we add New Color Button palette which is there in CKEditor 4.6.2

#6: No. Just do an update. Adding new CKEditor features must be done in a separate issue. This must do just an update. Nothing more, nothing less. Minimize risk of every change.

I made a patch. Please check my steps.

• Downloaded Drupal Core 8.3 dev version and Ckeditor 4.6.2
• Replaced build-config.js, CHANGES.md, ckeditor.js, lang folder, LICENSE.md
• Moono skin is retained
• Replaced plugins with the corresponding in CKEditor4.6.2
• Retained image2, sourcedialogue and widget plugins
• showblocks plugin is taken from CKEditor 4.6.2 full package
• Changed Version and License url in core/core.libraries.yml

I'm afraid I see lots of problems. For example, you modified build-config.js.

You shouldn't just download CKEditor 4.6.2. Drupal 8 has a custom build of CKEditor. You need to clone the CKEditor git repository, go into the builder directory and run sh build.sh -s, as is documented in core/assets/vendor/ckeditor/build-config.js. You'll need to use Drupal's own build-config.js, not the default.

Perfect! Manually tested, still works correctly. Thanks! :)

Also, 4.6.2 added the Azerbaijani language. CKEditor uses the az langcode. Drupal uses the same langcode. So this translation will automatically start working inside Drupal as well! :)

Yaay!! thanks, Wim Leers

Thank you, @boaloysius :)
