V4 - consider adding a header with power and user-defined FPGA pins.

If there ever is going to be an update of the Spec board it would be nice if it had a connector (say right angle 20 pins 2.54mm dual row) with the 12V power supply, ground and some FPGA pins. This would allow the Spec board to be integrated into stand alone products more easely (and connect a fan without soldering to the board).
