Baseball bat knock-out

[Faustie]

The baseball bat now has a 50% chance of knocking an opponent out if you hit them in the head. The damage has also been buffed slightly, from 15 base damage to 20. We wanted a new semi-lethal weapon for citizens to have that could combat the stun gun, and this fits the bill; it's much less refined and more brutal, as it's not government, but still effective, both for non-lethal and lethal combat.

We'll keep an eye on the balance of the bat. If it's too OP we may reduce the knock-out chance slightly.
