Adds support for TinyMCE 4.x.x (Removes support from 3.x.x)

[NullVoxPopuli]

• Pull upstream (nytimes) master
• Remove TinyMCE 3.5 related code
• Changed folder structure of plugins to match that of TinyMCE 4.x.x

Only thing left (to my knowledge)

• When building, the plugin files are named plugin.js instead of plugin.min.js (any help on that would be awesome)

Great work! Is anyone using this in production? It's hard to integration test against tinymce, and getting ice to adapt to new versions of tinymce has always been a huge pain.

[johanneswilm]

we don't, but we might in the near future.

It would be nice to see this request merged, as WordPress ships the version 4 of TinyMCE since WordPress version 3.9. So contribution for WP support depends on this.

https://github.com/TinderBox is using this in production. :-)

I'm hopeful about this plugin. Is it still being used and/or under active development at @nytimes? I'd love to make use of it with @tinymce 4.x.x and to contribute fixes and updates. Thank you!

@NullVoxPopuli Did you test this plugin tested on 4.3.x TinyMce?

[NullVoxPopuli]

@itmilos, I'm not sure. @jheth might be able to answer though?

[jheth]

@itmilos We are on 4.3.6 and continue to use this plugin. We have had to make a few tweaks to core tinymce over time but it has held up really well.
