[TASK] Set php header comment via php-cs-fixer

With this patch, the header comment of php files is
automatically added by the php-cs-fixer, which guarantees
that its format and place of occurrence remain the same
in all files.

Files that are copied over from other projects are excluded.

Furthermore, files that are kind of inspired by other
projects also get the same header comment but may have
a second, additional comment explaining its origin.

Used command:

    bin/php-cs-fixer fix --config=Build/php-cs-fixer/header-comment.php
