Redactor 3

[gr8bit]

All tests succeed, even the system/capybara tests (well, most of the time. Racing conditions seem to be racing).

Biggest changes for version 3 of Redactor (please review @GBH, I don't know if this breaks something):

• lots of additional plugins (5 of them bring a little CSS which I always included because it's so little)
• language/i18n files have been massively reduced (were the extra ones, e.g. "az", "ba", "bg", user contributed?) and have been partly renamed (e.g. "zh-CN" -> "zh_cn"), bringing them out of sync with the rails locales -> needs work

Let's finalize this together @GBH :) Do you have a real world project we can throw this into?

I just noticed this HowTo for a Reactor upgrade: https://github.com/comfy/comfortable-mexican-sofa/wiki/HowTo:-Upgrading-Redactor-Wysiwyg

I did not see this before, sorry. We'll have to go through that as well I guess.

@GBH fyi: we'll be using it in a project, so we're currently fixing everything that the update broke. :)

@gr8bit 👍 Rails 6 final release probably will happen this fall. I'll jump in sometimes then to merge everything in.
