* The cryopod simply qdel's the datacore records. Old garbage.dm hard-del()'d datums, so it was fine. Now we need to make sure they are actually removed from the data_core.
* Testing shows this fixes#1713 and in most cases the objects also GC cleanly. However some older computers still retain hard references to data_core entries. But even in the cases where that prevents a clean GC, the player is still removed from the manifest successfully and promptly, so that can wait.
