[TYPO3-core] TYPO3-CI: Activation of a new CGL-Sniff "TYPO3.Commenting.ClassDocComment" in ci.typo3.org

[Andy Grunwald [wmdb]]

Hi,

after cleaning up the TYPO3 core + system extensions i will enable the 
CGL-Sniff "TYPO3.Commenting.ClassDocComment" at ci.typo3.org tomorrow.

This will fix "Feature #38746 Activate CGL rule 
"TYPO3.Commenting.ClassDocComment" in ci.typo3.org-gerrit-slave" [1].
In the wiki of PHP_CodeSniffer you can find a code example. [2]

It is necessary to rebase your local branch to current master before 
pushing a new patch set to gerrit to avoid breaking the build and make 
Mr. Jenkins happy.
If you got any reasons against the activation please let us know.
Thanks for everyone who contributed to this!

Regards,
Andy
