Added MFR, MPN, Description, DST, and DPN to all components using the amazing KiCAD table properties editor. Yay KiCAD. Attemping to make the BOM be self-assembling.

Last changes to 6.1 after design review today.
...
Added logo.
Brought up to KiCAD 8.0.1.
Added text next to smpm connectors.
Fixed some 0.127 traces that didn't need to be that thin on nRESET.
Fix silkscreen refdeses on new components.
Move pin 1 marker on the BP0805A1308.
Remove thermals on PA bottom layer.
Added oresat-c3-eagle-import symbols and footprints so everything is local.

Fixed accidental deletion error in schematic on eMMC net, updated symbols and packages to match library, updated date on silk screen, and pushed UHF power supply out of the way of the frame boss so it can be used in more slots, including in the 1U slot 2.

Fixed Q1 in the I2C subsystem, which was backward but we never noticed. Removed hardware ID resistors and added back in test points, since HW ID is now stored in internal EEPROM. Updated power measurement values in UHF transmit path. Finally, added circuitry to enable USB lines over the UART backplane. This involves switching the UART signals for the USB signals, and pulling VBUS high to trigger USB on the Octavo. It's pretty janky, so we'll see if it works!

An evening of cleanups from the design review. Includes lots of ERC and DRC cleanup, although still over 450 DRC errors mostly from RF keepouts. Fixed PA ground connection, notes on pin reset configuration, and lots of small naggy things. Also cleaned up wierd broken traces on eMMC traces. No longer all same length (sorry Oliver) but it shouldn't affect performance.

Switched all grounds to a single ground, because I can't find a way to overlap ground planes in KiCAD. That's actually not terrible, however, because KiCAD has an anti-plane feature which I used to cut the ground plane between UHF and L radios and L radio and Octavo. So actually I think it came out better than having separate ground planes. Only thing left now are the ~ 40 connections to the Octavo.
