[Feature Request] Simulating the 'danger' and 'death' pheromones.

[Azoraqua]

As the title states, I want to propose the simulation of the following:

• Danger pheromone.
• Death pheromone.

---

Danger: When ants sense a threat, they emit the so called 'danger' pheromone which let its colony know that there is a danger present; Could be an intruder, flood or similar.

Death: When ants die (Or sense that they are dying), they leave a pheromone that signals the colony one or more of its colony is dying/has died and may cause fellow ants to investigate and 'bury the fallen'.
