Add support for CKEditor

[benthamite]

Setup

Browser: Chrome Version 96.0.4664.55 (Official Build) (x86_64)
Editor: GNU Emacs 28.0.50 / Sublime Text, Stable Channel, Build 4121

Description

GhostText works fine on most websites, but it fails on a few that I personally use very often. The foremost example is LessWrong. When I trigger GhostText from the browser, it opens a new buffer on Emacs with the text <p><br data-cke-filler="true"></p>. However, any text entered at this point is not sent back to the browser; on LessWrong, the comment field remains empty.

I downloaded and installed Sublime text, and can confirm that it exhibits the same behavior.

CKEditor is a WYSIWYG editor and it can't really be "supported" here because your editor would still need to receive the HTML and not plain text.

You have two options:

• switch to the "plain editor" in CKEditor so that GhostText can interact with the textarea
• Wait for html -> markdown -> html #53
