paragraphs 8.x-1.0-rc5

A whole lot of changes. We should be near to the stable release now.
Every release blocker we know of was fixed. We need your final feedback now.

Don't forget to update ERR at the same time to 8.x-1.0-rc7!

Most important pieces:
Paragraphs now builds on top of the entity reference revisions composite relationship. This needs a data migration on update.
This move allowed us to easily fix many previous bugs and limitations such as permission checks.
We have clean multilingual support now and previously inconsistent multilingual data is fixed.
The widget is only triggering a save on host entity save and only creates a new revision if requested. Previously every preview or ajax interaction created accidental revisions.
The UI received more attention to remove inconsistencies. It still feels like Drupal Core, with slight additional pieces in our added complexity domain of composites and nesting.

After all the hard work, we are looking forward to your excitement. We are all proud of the recent progress.
