Knightmare66 608814c830 Fixed firing player weapon while using spycam/remote turret in default Lazarus and missionpack DLLs. 
Fixed Tactician Gunner's flechettes going thru player bbox at point blank.
Made edict_t pointer arrays static in server, default Lazarus, and missionpack DLLs due to stack size concerns.
Added contact grenade mode for special monster flag for gunners in default Lazarus and missionpack DLLs.
