Railgun first iteration

What I want to do with this:
Create a weapon that has a random chance of hitting an organ in your
body, it will do rather small amounts of brute damage, but if it does
hit an organ it will bruise / break it, possibly doing massive amounts
of damage (Example being the heart, where you would pretty much
instantly die from oxyloss)

Missing:
*Code for the bullet to do random organ damge (60 brute as a
substitude right now)

*Sprites (Worked on by SocialSystem)
