Add Zend\Form dependency to composer.json

[arjanvdbos]

Because Zend\Form moved from required to suggested in the composer.json of Zend\Mvc you have to add Zend\Form as a dependency in the composer.json of ZFTool. Otherwise ZFTool throws an error:

Fatal error: Class 'Zend\Form\FormAbstractServiceFactory' not found in C:\www\project\vendor\zendframework\zend-servicemanager\Zend\ServiceManager\ServiceManager.php on line 311
