[TYPO3-core] RFC #16031: Feature - Implement new layout and labels for tt_content as result of T3UXW09

[Steffen Kamper]

Hi Joey,

thanks for this work, looks really good and well sorted.

There are some styling issues which should be solved after. Also this 
patch show a bug inside the palette render which shows a php warning on 
implode and leaves a br at the beginning if it starts with a palette.
I will solve this bug first (tomorrow) before committing this one, which 
means: +1 by testing and reading.
