- Fixed: With opl_onechip set the second OPL chip was never set to anything valid

so it contained an invalid pointer. There were also a few other places that
  simply assumed that the second chip is set to something valid.
- Fixed: NPCs which are engaged in a conversation should not move.
- Fixed: Player movement animation was not stopped when starting a conversation.
