Problem
Implement a final thrower ant that does zero damage, but instead applies a temporary effect on the action method of a Bee instance that it calls throw_at on. We will be implementing this new ant, SlowThrower, which inherits from ThrowerAnt.
SlowThrower throws sticky syrup at a bee, slowing it for 5 turns. When a bee is slowed, it takes the regular Bee action when gamestate.time is even, and takes no action (does not move or sting) otherwise. If a bee is hit by syrup while it is already slowed, it is slowed for 5 turns starting from the most recent time it is hit by syrup. That is, if a bee is hit by syrup, takes 2 turns, and is hit by syrup again, it will be slowed for 5 turns after the second time it is hit by syrup.
