Blocking the Road

OK, got the barricades in place and a miltruck set.  Still WIP.
Anti-materiel turret!

I said I'd make a .50BMG turret.  Single-shot antimateriel, damage is
surprisingly variable.  :-/
Mil-Block in place

place_spawns is horribly imprecise.  This installs a miltruck blocking
the N/S road and a pair of turrets, along with some milcorpses.
Generally it's dropped off some troops, but sometimes the heavy-duty
bots are out!
Bots upgraded

This makes the chicken walker and tank drone much more lethal.  The tank
in particular is a serious threat on foot, and can bang up vehicles
pretty good too.  (Fae help you if your gas tanks are near the driver!)
Ammo tweak

If you can dodge/soak 20 shots, you deserve to have it go dry.
Police roadblock

Adds a less-lethal blockage, with police and 9mm turrets.
Probability fix

Resets the map-extra probabilities back to usual.
Attack tweaks

What I was commenting on, and a translation note.
Tankbot vulnerability

Helps to let people find out about the Tiny Flaw in the otherwise
indestructible killing machine.
Targeting warnings

Let people know when they might be insta-killed next turn, so they can
take proper precautions!
