[Hero 5] Add ability: drag enemies in a direction

The impulse is fairly weak, but it has no cooldown (of course). As long
as you can reliably click on them, you can keep dragging them around.
This builds charge.

Portal now COSTS charge, rather than gaining it, so that you bully
people until you can build a portal.
