Somewhat fix for #3543, gave bees a placeholder icon_dead state and made it so bees don't move around while dead

* Stopped bees from moving around while deceased (in this case, while not having stat CONSCIOUS)
* Bees don't have an actual death icon yet, just a placeholder bees1 for now
* I don't think bees were meant to be punched/toolbox'd to death in the first place anyhow
