Subject: [PATCH] Add auxtemp header, stacking power connector

Managed to update the pcb order in time. Auxtemp header takes a DS18B20
chip as an auxiliary temperature monitor, good for checking for propane
tank freezing or even as primary temperature control. Additional
powerstack header allows stacked breakouts to pass power between boards
