[TYPO3-extbase-kickstarter] Roundtrip concept for the kickstarter

[Sebastian Michaelsen]

I just wanted to test the current version of your branch but end up in a 
fatal PHP Error

Fatal error:  Call to undefined method 
Tx_ExtbaseKickstarter_Domain_Model_Property_Relation_ZeroToOneRelation::setForeignClass() 
in /typo3conf/ext/extbase_kickstarter/Classes/ObjectSchemaBuilder.php on 
line 111

Is someone of the roundtripping team available for a skype meeting the 
next days, to show me the current status?
