Remove the bleeding and projectile embedding from darts.

[Roomba]

I think it would be helpful if bleeding damage from the tranq rifle was lowered, though. It's currently more lethal than some actual traitor weapons, which feels a little off. Currently trigger-happy MDs really like emptying it on hapless assistants trespassing in medbay and leaving them to bleed out and die, whereas the one in the armory rarely gets used because even when there's a HOS around it's too lethal for normal sec work. Considering what the tranq darts already do, the bleeding damage is just overkill. If you lowered the bleeding damage you could make a case for moving the armory one out to sec proper so you have an actual counter to geneticists who use SMES human to make themselves taser-immune, and vigilante MDs become a little less murdery.
