DOWN WITH THE RIFTWALKER!!!!!!!!!!!!!!!!!!!!!!!!!!!

Shadowstep's fail safe action - push towards ally well - may need to be changed to follow pathing, because the current functionality does not look right in the opposing team's top and bottom lanes. I have not decided whether the added complexity of implementing this would be worth it. 

In addition, Shadowstep could use some more API to improve prediction, namely: Cliff detection, target's current movespeed, and a way to check if the target is turning.
