Corrected optic scope positions for all guns

Fixed M4 issues

- Adjusted cornershot boot up animation

- Added the AUG, a three-round burst rifle.
- Added Cornershot attachment, which gives you a view of what you're shooting while you blindfire.
- Added shotgun Slugs.
- Nerfed Remington 700. It will now require a hit to the torso or head to one-hit kill, and its aim down sights time is slightly worse.
- Buffed Ultima Ratio with slightly better handling so it can compete with the Remington better.
- Buffed DSA-58 with better recoil and accuracy, hopefully making it somewhat usable.
- Shotguns are substantially more accurate, and benefit from head/chest multipliers.
- Fixed missing iron sight textures.
- Recoil now automatically resets when you stop shooting. This takes into account if you have manually compensated for recoil!

- Added DSA-58, a new slow-firing assault rifle.
- Added Fast Reload perk
- Added Smackdown perk

-Fixed customization issue

- Fixed some MP stuff
