Button's pads labeling on the IPS-Board are swapped (UP <-> DOWN, LEFT <-> RIGHT)

[Bhgp-git]

Hello,

First of all, thanks for this amazing project. I finished mine own DMGC yesterday, and it is so nice :).

During the assembly/testing I have noticed that the labeling on the pads on the IPS board is swapped: up is down, left is right. The function itself is right, only the labeling is swapped.
