New feature: Deadzone Aiming

I am personally a big fan of deadzone aiming, and it's something I've wanted to implement since the project's beginning, though I only got the idea on how to do it first today, and thankfully the implementation worked out swimmingly.
This effect is toggleable in the menu, since I understand most players tend not to like this feature.
Another feature, which you can see in the gif, is the ability for enemies to be downed by hits. This disables them and makes them writhe on the ground.
Additionally, I've changed the way blood decals are formatted, which allowed me to use a different shading model which reacts better to lighting, so now the blood blends more nicely into the environment whereas before it looked unnaturally bright.
Beyond this I am continuing to work on the demo level. Part of it can be seen in the gif above. Stay tuned ;-)
