Admin WYSIWYG upgrade to latest Tiny MCE 4.*

Feature request from darrenjennings, posted on GitHub Oct 23, 2016

On latest mangeto version, would love to see TinyMCE upgraded and maintained since Magento is several versions behind latest TinyMCE. https://www.tinymce.com/

Newest version should include integration with image uploading/resizing/editing, magento widget/variable insertion etc.

I've attempted to upgrade the core myself so as to offer a PR, but it broke too many things along the way.

I was able to get TinyMCE 4 working with Magento 1.7. Will post a PR here if I have time to get it working with Magento2.

thanks @darrenjennings new features in the latest version look really interesting so I'd imagine a PR would be very valuable for the community

@tkacheva please review in context of upcoming CMS work

This would be great!

This seems well overdue at this point. TinyMCE is a large part of the code that seems concerning it is so out of date.

The code has been exempted from being minified which is probably due to the lack of code that won't work in 'use strict'.

The code also is difficult to audit for security because of it's size and complexity.

Magento 2.3 release will include TinyMCE editor updated to the recent version. Integration with images/magento widgets and variables is done via plugins

Great to hear that! For those using the 2.1 or 2.2 branch: I have written a module which upgrades the core editor and also covers the customized widget plugins, currently working for Magento 2.1 and Magento 2.2. For those who want to check it out:

Very important to do so!
