Inspired by the Payday 2 equivalents included in Restoration Mod and/or Subsimple's Standalone Static Recoil mod.

This mod eliminates re-centering aim assist (yes, even on PC). When you fire a shot, your sights/dot will shift according to the gun's stability. This will make follow-up shots harder to put on the same target.
You will have to manually re-aim your gun in order to hit the same target.
The muzzle climb restriction has also been removed. Now your muzzle will forever float towards the heavens as you unload.

The previous weapon rebalance was used as a base for weapon values (see changelog), although with changed recoil and accuracy values.
Vanilla recoil values were quite odd and non-sensical (negative recoil values as well as Steelsight stance having the highest recoil for certain weapons), so they would not have given pleasant results with Static Recoil.

Accuracy of all weapons (excluding shotguns and grenade launcher) were increased by 10% (equivalent of Sharpshooter Crew Bonus) as a counter to the new weapon handling difficulty.

Side effects: Tazers will pull your aim down hard.
