Move the +5V pin on the endstop connectors 2.54mm further away from the Signal pin, creating a 4 pin connector, keyed with a gap (previously discussed).
This will stop people putting endstops that use both ground and 5V in back-to-front (eg: optos and hall-o's), and frying them. Also those people making their own boards using microswitches can leave out the 5V pins altogether (by enabling the pull-ups using JPB01).
