Originally was going to make them do increased damage to structures but
its already 30 force it'll crack open most things with no issue

## Why It's Good For The Game

Gorlex uses mining tools like this sledgehammer in lore, its reflective
of their origins and is also cool as hell.

## Changelog

:cl:
add: Adds the Gorlex Marauder Breaching Sledgehammer, for both utility
and combat. Available in the black market.
