Pulling the teeth from bees, lowering halloss regen

Bees do a lot less damage now, no longer hit you from seven tiles away, no longer go through windows or windoors (In so much as DirBlocked() allows), and no longer target anyone but the person who pissed them off. Unless that person disappears from sight. Then they'll target anyone else around until they stop being pissed. Also, they'll harvest from all plants and benefit from all flowering plants, not just harebells and sunflowers. 

Toned down halloss regen. Coming soon: Weaken when hurt so bad.
