Currently we use a mix of PSR-2 for new code and eZ coding standard (v2) for all existing code.

This causes some frustration and time loss switching back and forward, so we should fix this sooner rather then later as it has been decided to make this change anyway.

Optimistic assumed tasks:

• first test https://github.com/FriendsOfPHP/PHP-CS-Fixer on ezpublish-kernel to see how it is able to do everything for us, if not we have quite some more work to do.

If that goes well:

• change for all repos
• change ezrobot
• enable ezrobot for more repos (consider setting it up for organization and have config file in it to configure CS/test checks)
