Teacup changes

I've had a look to the changes offered for Teacup, pinio.c. Didn't follow Sanguish development closely, but I see you keep the PSU pin as output, even with the PSU turned off. This way you not only miss initializing the pin right after a reboot, you also conflict the 5V signal from the ATmega pin with the 5V signal from the power supply (if they differ, e.g. 4.9V to 5.05V, a current flows). Also, setting the pin as input when the PSU is turned off allows to override the ATmega command with the typical paperclip method.

Is this change intentional/required?

Also I hope you agree to put these changes into Teacups' repo.
