Fixes thrown items not dealing enough damage

Created by: unid15

Once an item is thrown, it has a speed variable. In theory, higher speed meant more damage, and (in case of sharp items) pinning to walls In practice that variable was never transferred to the hitby proc, so it defaulted to 5 holy fuck

Before, pneumatic cannons were completely useless because no matter how hard they shot things, the impact speed was 5 Now, pneumatic cannons cranked to maximum and filled with cleavers deal 100 brute damage to a naked human

Pinning to walls is disabled and I'm working on re-adding it but it's going to be in another PR
