- Small bug fixes

- Now the player can choose between 2 weapons at the beginning of the mission
- Added more ammo to the player and also to your teammates (Number 4 also carries some extra ammo for player)
- Added hidden optional objective (contains also some useful equipment for player)

- Tweaked a bit enemy AI skill (mostly lowered)
- Some enemy soldiers at the objectives will not appear at lower difficulties
- Also at lower difficulties the enemy around the informant will open fire at him a bit later
