M60 ammo changes; now 500. To make it more viable.

Balancing

- Ammo reserve buffs
- Pump and auto shotgun ammo buffs;
- Let's assume the M4 Benelli is the military 7-shell tube variant
- Pump shotgun in game is not only based on the Police Magnum but also the Ithaca 37;
- Pump shotgun's tube is not visually that much shorter; ammo buffed to 5
- Ruger Mini-14 and G3 damage buffs

- Scout clip reduced to 5
- G3 damage buffed to 100
- Negligable changes

Nerfed scout ammo + widened shotgun yaw and pitch

Further balancing; Akimbo reload is longer, fixed values for autoshotguns, sniper balancing, etc.

Tweaked damage values. Subject to change.
