Default Launcher Rotation (Remove)

Can anyone tell me how I would go about modifying the .apk or .smali code to stop launcher rotation? I know by default it's off, but I downloaded biggin's ROM and even tried a couple of different 5x5 and 4X5 launchers and they all seem to rotate. What I'd like is the S5 Launcher in 5X5 orientation, but without screen rotation. Any help would be greatly appreciated.
