## About The Pull Request
Adds bloodroaches.

These are cockroaches that have gorged themselves on blood in
maintenance. They're very gross!

Splatting one causes an explosion of blood all around the death
perimeter, splashing both turfs and mobs with blood.
They have a 1% chance of spawning in place of normal roaches.
They also spawn in:
- Abandoned crates, replacing the 30 roaches with 30 bloodroaches.
- As backup anomalous crystal possession targets.
- Grimy fridges
Added a trait given to things killed by pest spray, used to check on
death explosion for bloodroaches.
Changed roach spawns in maps to use mob spawners, so I can replace them
with bloodroaches 1% of the time.
## Why It's Good For The Game
Splatting a random roach in maintenance that explodes into blood sounds
hilarious. It also adds janitorial depth by requiring pest spray to
carefully eliminate these pests
