Please update to work with CKEditor 4.18

I'm trying to install this plugin on a Invision Community instance and I am getting 'invalid plugin' errors.

Hi,
I've just tried the plugin with 4.19 and it seems fine when I manually place the plugin in the plugins folder on the installation (rather than use the CKEditor builder).

However, I've just released a new version of this plugin in the Addons repository, so hopefully that will work now. Honestly, I don't have time to test that out unfortunately.
