add visual indicators for suffocation damage

[TheOnlyRyan]

A blue overlay isn't actually that hard to implement, i'd imagine it could borrow some code from the paint can and just apply it to that.
Although it'd just be for skin, rather than fully blue-ing someone, and wouldn't be good if it was smurf 100% blue, but an off white blue instead.

And i'd be against examining, because that just sounds too easy and is kind of redundant if you're a doctor as you're going to have prodocs on anyway. Having it visual means that if a player is suffocating and is wearing a gasmask + glove you aint going to know apart from the gasping, which is good, it's balanced. Seeing someone waltz into medbay visibly blue means you can fast treat them for oxygen deprivation.

But if they're all covered up and laying on the floor you can see they're unconscious or dead, you can even see if they have a stupid expression on their face?

You can't have one without the other. If someone is suffocating then they're not just going to stand there and look normal, they'll be grasphing for their throat, trying to rip off their gas mask. It would be very noticable, and with a game like SS13 which a great deal of is text based descriptions I think this would help.
