Implement raw edit mode in Zebra

[hlubek]

The most straightforward way to implement the raw editing mode would be to render it in Zebra with generic components (in Preview if the current editPrevieMode is rawContent).

For that we'd need to re-implement the Fusion based raw content mode rendering and add the CSS dynamically.

For now, what do you think about shipping this config to deactivate this not working editPreviewMode?

Yes, we could add this to Settings.yaml in Networkteam.Neos.Next.
