Let's fix bloodbags.

Created by: 9600bauds

Actual Bug: Bloodbags that are supposed to spawn empty instead spawn as "Murky Bloodpack" containing 200 units of typeless blood, which effectively works as O-. This means the bloodbags that are supposed to spawn empty in Medbay, and alarmingly enough, bloodbags created from plastic sheets (yes, you can make blood from plastic).

Balance/Discussion/Feature Request/Whatever: As of right now, Medbay spawns with about 5 "universal" bloodbags. I feel like this is what it SHOULD be like, as otherwise you run out of blood extremely quickly and your only other options for O- blood are to powergame and set yourself to O- in character creation, or humanify all the monkeys in Genetics and test them all manually. Blood loss is already hardcore as fuck, blood transfusions are already tricky. If you add bloodbag shortage on top, it just ends up in doctors letting bloodless people die and cloning them.

Addendum: You can technically also make typeless blood from blood tomatoes, but it's extremely unviable to do so since you can't put that blood in an IV drip.
