Make some facial hair styles prevent gas masks activation

[BalthazarArgall]

Summary

Features "Some facial hair styles now prevent you from using gasmasks"

Purpose of change

Santa can't wear a gas mask.

Describe the solution

Big beard = no gas mask, mustache ok though.

Describe alternatives you've considered

Invert the if statement and check for a GASMASK_COMPATIBLE flag, I dunno, maybe it's more intuitive?

Testing

Tried activating a dust mask with a beard, couldn't.

Additional context

Let's have a debate about what facial hair should be gas mask compatible.

Do tell me what you think about what facial hair I chose to make incompatible.

[DSeyka]

One would expect facial hair (and other appearance traits) to be a purely aesthetic choice without any gameplay ramifications.

I think this might need a feature that allows us to cut the facial on the spot with scissors or a hair trimmer to lessen the frustration. Not to mention this would cause inconsistencies like people with afro hair being able to wear a full-sized helmet.
On the other hand, DSeyka is right. Many people wouldn't like it.

Off the top of my head, before delving into the files, we’d need some way to shave or trim facial hair. I know we have shaving kits, but come to think of it, I don’t know if they affect beard length at all. Second, we should probably note this down in some player-facing way so people with no knowledge of gas masks don’t amble off into a toxic area with a full Santa beard and then have the unpleasant surprise that they cannot, actually, use their mask. It’d be nice if this were viewable in a reliable way around the world. For example, I wrote a CBRN training video description for the E logs, but we should have this noted in the gas mask’s description in lieu of that.

while i acknowledge that there is a very reasonable logic here, it's important to note that we've been making it a point to keep certain things that exist for player identity -- including selected gender, and the various cosmetic traits -- as purely cosmetic, with no in-game effect.

this pr conflicts with that, and so unfortunately neither this nor anything similar to it should be merged.
