Add extension/Resources/Private/composer.json again. Makefile: add composer update again. Necessary to deliver phpoffice in extension/Resources/Private/vendor/phpoffice.

This reverts commit 571b5b6a

Remove vendor/autoload.php and vendor/composer/ from Makefile - the problem was a autoloader in report/Excel.php

Refactor: Manual.rst update config variables (reorder), add 'qfqLog'. Support.php: formSubmitLog hardcoded to fileadmin/protected/log. DOCUMENTATION_QFQ > SYSTEM_DOCUMENTATION_QFQ. Remove config var 'logDir'.

B3464: FE.type=subrecord, mode=readonly - fixed that sub form should be open with 'formGlobalMode=readonly'

phpunit: fix problems. Revert change in cb2e2a70: if a record lock exist, another form, with record lock mode=NONE, can't get write access to it. This is what the manual describes.
