51410: Nudge Objects To Arch
Used by the routine at HandleNearArch.
Gives the player a small push towards the middle of a door, when it is standing in front of it. The push is along x or y, depending on the direction that the player is facing and the type of the door. That way the player does not have to line up exactly to go through.
