Changes

* Leap can be used everywhere, even in levels with a low roof.

* Leap Attack has very long range with just a single point, and is quite helpful to hop over obstacles.

* Like [[Leap]], and unlike [[Teleport]], Leap Attack will not take the [[Barbarian]] over walls or other obstacles that block his line of sight.

* Leap Attack knocks back monsters near the landing zone, much as Leap does.
