Collision now uses bits and masks. The main upshot is that ghost and ice/directional blocks collide much more correctly, now. And turtles block fireballs. Also, monsters can now move over "no" signs, and can trample the player if she's standing on top of an item. While I was at it, I finished implementing the "bestowal bow", an item mod (same layer as the "no" sign) that allows any actor to pick up the item in that tile.
