Removes Virology (#8927)

-Almost all aspects of virology and it's related machinery and objects have been purged from the code and map.
-Most of disease code has been purged. Some pieces of it remain as holdovers because they would require extensive rewrite of defines and codes for things like nanite robot transformation and appendicitis (that frankly isn't necessary)
-The outbreak event has been purged, as has the virology malicious code event variant.
-The Virology department has been remapped into the Abandoned Sector.
