Clean up blood bag code
Created by: Probe1
Those empty blood bags stay labeled as empty blood bags forever. Right now the only thing you can do about it is label it with a hand labeler (which medbay fortunately has) and hope people ignore the EMPTY BLOOD BAG portion and read the (FILLED WITH O-) portion.
Can't we fix this up somehow to look better? Maybe remove 'empty' and just have them called blood bags. That way they don't look dumb when they're filled and still labeled as empty despite clearly being filled.
Second part to improve blood bags - have their unit amount displayed on shift click. If the bag has half the blood left let it say that. Either precisely (110 of 220) or vaguely (looks about half full) or however you please. Those two things would really polish up blood bags.
