fortifications industrial citadel turret accuracy patch

Fixes turret accuracy by removing ShootingAccuracyTurret from their stats.
ShootingAccuracyTurret lets you specify a chance for a turret to not miss per cell of shot distance.
This means that if you set it to 90%, you have a 90% chance to hit if the target is one cell away from you. At 5 cells it's already down to 59%. At 20 it's 12.2%. And it's a base chance, meaning that the turret gun's accuracy is factored on top of that.

So basically those turrets literally can't hit the broadside of a barn without this patch.

This is just a simple patch, so it should be compatible with any rimworld version. Again, it literally just removes a single xml node.
