Christoph Oelckers e5dc92f998 - some reshuffling of save data so that the actors won't get restored before the sectors. 
Note that this required splitting P_SerializeWorld, because sector_t and FSectorPortal contain some actor pointers, for which the same rule applies: Portal linking can only be done after all sectors have been read, meaning it cannot be done along with the rest of the data in these structures.

Obviously such a change breaks savegame compatibility so the min. savegame version had to be increased again.
