Added night vision effect for turret camera (last camera)
Added thermal vision effect, this will work only in EFLC, some Icenhancer/ENB can make this effect don't work properly, but this is not big deal, use night vision if thermal don't works fine :)
Added new HUD with damage and weapon usage bars
Improved cop's cannons
Improved cop's rocket aim, now they will shoot more but dont will cause too much damage like instant car explosion
And fixed some issues...
