[CLOSED PR] New gun addidtion to the "support" sec loadout

[Flaborized]

Don't really like this at all, I feel like the haloperidol shot would get the most use by far and it kinda stomps over the existing niche of tranq rifles. I'd rather the support class continue to not have a ranged weapon and it be designed around *that* because I think it's an interesting alternative way to play sec, and making it viable through good non-ranged-weapons would lean more into that. Also not really huge on the sprite design, it *looks* like it should be firing something more energy based and less chemical to me. :eye:
