Prepared services for autowiring. Services now have aliases named the same as the class:

• doctrine_phpcr => Doctrine\Bundle\PHPCRBundle\ManagerRegistry
• doctrine_phpcr.session => PHPCR\SessionInterface
• doctrine_phpcr.odm.document_manager => Doctrine\ODM\PHPCR\DocumentManagerInterface

Removed deprecated PHPCRODMReferenceCollectionType and ReferenceManyCollectionToArrayTransformer.

Dropped deprecated option session (use dm instead) and unused option name from command doctrine:phpcr:fixtures:load

Dropped deprecated option session (use dm instead) from command doctrine:phpcr:document:migrate-class

Made all command options required - omit the option completely when you don't need to set anything
