Experimental Branch Update

Fixes

Fixed bug where enemies would pop up and fly away sometimes when stabbing them.
Enemies now use the true aim of their guns and can no longer shoot the player if they aren't physically pointing it at them.
Fixed bug with neck shot damage.

Changes

Re-balanced gun damage. Guns are more powerful across the board.
Re-balanced enemy downed state. Enemies are more likely to enter downed state and take multiple follow-up shots before death.
