Add some digikey order informations to components

Add some little changes to the schematic, add calculations

Move processor part a bit down

Add oval mounting holes to support NEMA23 as well as NEMA24

Improve board routing, add some dukos

Improve pcb

Improve pcb routing, add testpoints and etc. The design improves a lot. Still lots to do, but most important design parts should now be drafted almost complete.

Improve driver part of PCB I think I improved the Driver part of the PCB quit a bit by rearanging all of the components. But there are still many points which have to be worked on. This is still only a routing test. Later I will create usefull copper lines and adding copper zones for all high current lines.

Place some components onto the PCB

Fix some assignment problems because of wrong library/component names
