TYPO3 Core

in class.t3lib_tcemain.php line 3468 and 3477 $swapVersion['t3ver_stage'] and $curVersion['t3ver_stage'] are hardcoded set to 0.

- the check if the swaping record contains the "delete online version" flag t3ver_stage=2 (line 3500) allways fails, deletion of online records from a workspace is impossible.
- the check for "new-placeholder" (line 3536) fails as well, placeholder records remain in databasetable
