Tiny but important fix for Nun's power

An Ankou

Death is not the end. You’ve been chosen as the Ankou, a servant of Death who aids lost souls using the tools of your old trade. Roam haunted lands to find resources, craft weapons, and slay hordes of demons in this action-exploration roguelike.

- Now Added the possibility of using the "Force Push" of the Nun even when not moving. It was kinda ok with a gamepad, but definitely NOT with keyboard and mouse. Note for "future self": try to remember to do the important stuff when a colleague keeps telling you something should probably be changed.
