[MANUAL MIRROR] Adds a new event, "Radiation Leak" (#19075)
Adds a new event, "Radiation Leak" (#72655) Adds a new random event, "Radiation Leak". A random machine in a random department will begin leaking radiation. This includes a radiation aura around it, and semi-regular puffs of smoke clouds containing mutagen and polonium. The machine will stop leaking after some time, but can also be stopped by using a random tool on it, indicated in its examine text. I added a new "radiation emitter" component, for simple "emits radiation" behavior. Then I made the radioactive mutation use it. This means that the radioactive gene emits radiation while on stasis and dead, rather than only in life. Co-authored-by: MrMelbert <51863163+MrMelbert@users.noreply.github.com>
