Diseases (#7057)

* Disease system first pass

* Renamed HealthChange

* First working version of diseases (wtf???)

* Fix the cursed yaml initialization

* Pop-Up effect

* Generic status effect

* Create copy of prototype

* CureDiseaseEffect

* Disease resistance

* Spaceacillin

* Nerf spaceacillin now that we know it works

* Sneezing, Coughing, Snoughing

* Fix queuing, prevent future issues

* Disease protection

* Disease outbreak event

* Disease Reagent Cure

* Chem cause disease effect

* Disease artifacts

* Try infect when interacting with diseased

* Diseases don't have to be infectious

* Talking without a mask does a snough

* Temperature cure

* Bedrest

* DiseaseAdjustReagent

* Tweak how disease statuses work to be a bit less shit

* A few more diseases

* Natural immunity (can't get the same disease twice)

* Polished up some diseases, touched up spaceacillin production

* Rebalanced transmission

* Edit a few diseases, make disease cures support a minimum value

* Nitrile gloves, more disease protection sources

* Health scanner shows diseased status

* Clean up disease system

* Traitor item

* Mouth swabs

* Disease diagnoser machine

* Support for clean samples

* Vaccines + fixes

* Pass on disease resistant clothes

* More work on non-infectious diseases & vaccines

* Handle dead bodies

* Added the relatively CBT visualizer

* Pass over diseases and their populators

* Comment stuff

* Readability cleanup

* Add printing sound to diagnoser, fix printing bug

* vaccinator sound, seal up some classes

* Make disease protection equip detection not shit (thanks whoever wrote addaccentcomponent)

* Mirror review

* More review stuff

* More mirror review stuff

* Refactor snoughing

* Redid report creator

* Fix snough messages, new vaccinator sound

* Mirror review naming

* Woops, forgot the artifact

* Add recipes and fills

* Rebalance space cold and robovirus

* Give lizarb disease interaction stuff

* Tweak some stuff and move things around

* Add diseases to mice (since animal vectors are interesting and can be used to make vaccines)

* Remove unused reagent
