Backbone Pinout Revision 5

The Servo Module forced me to think about isolation and made it obvious that I need 2 x 5V supplies in cases where 5V is used for Servo’s etc. I removed 48V as option simply because 48V is used for higher effects/currents. Pin 23/24 is now the 5V MCU supply that must stay isolated from the 5V/12V/24V PSU’s.
