2ebce55aa4 SIMtrace: Improve PCB routing of GND, 3V3 and VCC traces 
We have to make sure the impedance of the supply lanes is not too high.
Particularly bad was passing GND in 0.2mm under several resistors before
even reaching the LDO from the USB socket.

This attempts to address the major issues.  Also, the input capacitor is
moved closer to the LDO once again
