+ Fixed an issue with the turrets

+ Fixed error with both turrets : [Mannable NPC Turrets] lua/entities/npc_manned_turret.lua:167: bad argument #2 to '__add' (Vector expected, got nil) 1. __add - [C]:-1 2. FireMountedTurret - lua/entities/npc_manned_turret.lua:167 3. unknown - lua/entities/npc_manned_turret.lua:118

+ Made the grenade that is fired from the explosive turret no longer damage the NPC Manning it and their allies.
+ Made the NPCs that man the turrets freeze to restrict them from moving around.
+ Made them do the sequence once instead of them doing it over.

+ Added the ability for some VJ Base SNPCs to use it. ( Only Some of them from Military and Black Mesa SNPCs. )
+ Added a way to get rid of their weapon.
