Add shoot-in-direction-you're-facing for controller bindings of "projectile" and "zone" spells

For spells like Ray of Frost, Cone of Cold, etc it would be good to be able to just fire it in the direction that your character is facing, rather than having to lock on to a target first. Fire-directly-ahead-of-you works well in games like Diablo etc. Seems natural that it would work here too if it can be done.
