[TYPO3-team-core-v5] [!!!] @subpackage and @package no longer used, file level docblocks gone

[Karsten Dambekalns]

Hi.

I removed all @subpackage and @package annotations today, as well as all 
file level docblocks. Documentation and CGL on one Page have been adjusted.

This was because those things were merely used to cater pre-namespace 
neccessities and PHPDocumentor requirements. We don't use that any 
longer, so...

Regards,
Karsten
