Enabler: Disable pasting images into the WYSIWYG

[blairlearn]

Don't allow users to paste binary objects into the WYSIWYG editor.

If a user attempts to paste a binary object (e.g. an image) into the WYWIWYG editor, CKEditor will happily turn around and base64 encode it, resulting in a large amount of data being stored and the CMS no longer being able to load the page.

This needs to be prevented.

Potentially, this can be addressed via the Advanced Content Filter. The suggestion is to "create a CKEditor package without the image plugin."

Another possibility: a plugin to block images from being pasted: https://camerongregor.com/2016/11/14/preventing-pasting-of-images-in-ckeditor/

If I had to guess, these are objects in Word documents.

Unsanitized pastes from Word Documents are the source of much suffering.
