Breathing - Add cyanosis diagnose

[MiszczuZPolski]

When merged this pull request will:

• Add cyanosise diagnose with 4 settable levels:

1. No Cyanosis - 100% SpO2 (no settable)
2. Slight Cyanosis - over 90% SpO2 (default)
3. Mild Cyanosis - over 75% SpO2 (default)
4. Severe Cyanosis - over 66% SpO2 (default)

Because some groups doesn't use lethal SpO2 value or have it different from default 65%, all levels are adjustable.

To do:

• Translation for more languages ._.

The level of "no cyanosys" could be modified to be at least over ~95%? Or make it settable?
I reckon that 100% is good for gameplay perspective, but from a immersion perspective a slight cianosis at 99% would mean that 3/4 of world population is cianotic.

This is a shoold-aged population but the concept is similar

And this without accounting for blood loss that could make cianosis even harder to detect, although i guess that such code would be much more difficult to implement

I don't mean to denigrate it, it's a great idea imo beside this detail!

I know IRL normal person would have SpO2 lower than 100%, but for gameplay purpose i want to keep it as 100% - that means when someone is injured (for example hidden pneumothorax) medic would know this.

After commenting this i will add commit for medical level required so Anyone, Medic or Doctor could only detect it based on setting.
