Debugging

Loading the game shows that m_pTarget is NULL for a ferian, even though its state is stateAttackingThreat. We crash trying to access a NULL pointers.

Looking at the code there were a few things that could cause this:

• If we sent a Communication, with msgAttack (or msgAttackDeter) and pParam1 were NULL, then we could get into this state. I added some code to prevent this. However, I checked all calls and I couldn't see a way for this to happen. It's possible for an objCommunicate call to do this, but there are no such calls to a ferian.
• Another possibility is that at save time, we NULL'ed out the pointer because it was an object in a different system. I haven't found a way for that to happen (although it could have happened in a previous version). I added safety code in the ferian AI to handle the case of a NULL pointer. This also fixes the old save file.
