2715446c01 Board layout changed
I moved the components on the board around to give a better visual
representation of the components of the infnoise; USB protection,
filter, divider network, and then where the actual magic happens.  Vias
galore, but ERC and DRC satisfied.

4c9b8869e6 Board clean-up, parts updated from modified library
Schematic:
- Only updated parts from the modified library
Board:
- Moved parts, vias, onto mm grid (was arbitrary?)
- Major re-tracing to keep traces on-grid
- Added full board ground planes (both sides) with grounding vias
scattered around - edges are now fully grounded.
- Moved some parts around beyond grid, e.g. C6 closer to VCCio
- Added 'INFNOISE TRNG' to tNames
Notes:
- Passes ERC and DRC (based on originally included OSHpark Design
Rules), with the exception of the slot pads for the USB connector
(originally approved).
