Regression with Boltgun

[weeping.moon]

Part of the bulwark mini-rework.

Bulwarks

• Added a slightly faster light stagger animation.
• Removed possibility to spawn big packs of Bulwarks as patrols, reduced amount that can spawn simultaneously as roamers.
• Removed the “force field” in front of Bulwarks that allowed them to block hits/shots that didn’t look like they would be blocked by their shield.
• Increased health by 33%, and set lower stagger resistance during attack animations.

@FatsharkStrawHat

Increased stagger threshold for Crushers, Bulwarks, Plague Ogryns and Chaos Spawns.
