Important: #68758 - Command controllers allowed in subfolders

See forge#68758

Description

Extbase command controllers can now reside in arbitary subfolders within the Command folder. This allows for better grouping and namespacing of commands.

Given a command controller resides in my_ext/Classes/Command/Hello/WorldCommandController.php, it can now be invoked like this:

typo3/cli_dispatch.sh extbase my_ext:hello:world <arguments>
