closes #1036

The new post link is live, we can now enable publishing and saving in production.

Couple of things going on with this that I don't think are 100% related to this PR, but I came across while testing.

#1: I didn't notice while testing #1065, but if you edit a post that already exists, using Gutenberg, it will highlight the Gutenberg > New Post submenu.

#2: Our "dirty" checking doesn't seem to update when you change the text of a block until you click outside the block. It would be nice to be able to type some stuff then be able to hit the update button right away.

It does seem prone to race conditions, but in my testing I was finding that it saves content correctly when following the flow you described?

To clarify, the saving works correctly. I mean that it doesn't seem like you can hit the update button if you type some text and just sit there. Let me make a gif, give me a moment.

Like discussed with @mtias I updated this to display a confirmation when publishing new posts. We'll drop this confirmation once we have frontend support.

@BE-Webdesign To clarify the behaviour of the onChange handler of the Editable:

It works like this because it's hard to get TinyMCE work in a controlled way. We limit onChange calls to focusout calls only to avoid some issues we were seeing (focus jumps...), but this doesn't mean we can't try to enable it right now, we had several improvements in how content and focus are updated in the Editable, it could just work right now.
