- Updated tranquilized star effect code because the hook for rendering it somehow rendered it even while it was inactive

- Added Melee Arts 2 damage workaround

- Added kill credit fallback in case tranquilized player dies due to world damage while tranquilized

- Added a syringe
- Tranquilizer Gun now uses its own custom ammo type (tranq_darts). A basic entity ammo box for both the gun and syringe exist now.
- Added server convars tranq_blackout_enabled and tranq_admin_immunity. The former enables/disables the blackout effect and the latter enables/disables admin immunity to the effect entirely.
