[TYPO3-core] Deprecating Frontend Output "tidy" option

[Benjamin Mack]

Hey everybody,

see
  http://www.w3.org/People/Raggett/tidy/
and
  http://w3c.github.io/tidy-html5/

of what tidy does. Sounds like an extension to me :)

I see if I can come up with something for TER and 6.2.

... Clean and lean core - happy benni.

All the best,
Benni.
