Temporary solution to #367 while awaiting clarification from @Heinermann

Skip setting bEntryFlags to 0x04. This got the replays rolling again and normal single player automation also seems to work fine. 

This is just a temporary black box fix in order to get the data mining people on track. Review/clarification from someone familiar with the internals of the BW binary is required to make sure it doesn't lead to any unwanted side-effects.
