udpates:
- updated add-on and handheld boards
- updated detector 4pin to 5pin smd ribbon (added space for DetVcc to avoid using the TL1963
- updated main and add-on 12 pin to 16pin ribbon, moved some pin positions to make connections easier, added DetVcc.
- bypassed the switches for the alternative LEDs and detector (shows up on DRC check - ignore)
- on add-on board, left DetVcc hanging - connect where you need to (robert)
- double check before shipping - some odd things got shifted around so it's worth another glance
