Uploaded board design and OSHPark submission files.

My Zero arrived today after being listed as "processing exception" status in New Your for several days. Sounds like something I'd encounter after running a wonky kernel module, not something involving shipping...

Board is ordered. I'll order parts in the next couple days.

I tested leakage from the inductive coupling. Magnetic shielding doesn't work, but a bit of aluminum tape should work, with only a little loading of the coil. The real test is to see if a Zero locks up when mounted. I've got my fingers crossed...
