pin spacings

b33de16ac9 "fix" grounds by tracks into pour 
"finish" routing, ignore DRC violations from disconnected usb shield on
pin 6.

Add boot0 jumper pad "just in case" but really kinda dumb, we've got a
debug header on it. Why bother with this?

Change paper size in schema to get more space.

TODO: add silk?
TODO: replace "arduino" shape with just the pinpoints.

cb376f3959 WIP: hardware test partner round 1 
Not sure which kicad files are necessary and which are local yet!

Goal: fixed "host" board (this board) with socket for _any_ Nucleo64 st
board, giving access to test:
* DAC->ADC (both directions)
* I2C (both directions)
* SPI (both directions)
* Uart (both directions)

a socket for a cheap fx2 based logic analyser will be included, so that
sigrok can be used to capture tests of the actual line states.
