Order some relevant reference designator. Use JP for all jumpers. Place
silkcreen neatly. Add some custom silk screen. Remove heat sink corner
marks on silk screen.

Changes:
Footrints:
-Modified DC Jack to accomodate CUI PJ-002A
-Modified RJ45 to increase clearance between shield and poe pins
-Modified m.2 mounting pads to avoid drc errors
Schematic:
-usb-c facing usb mux is supplied by +3v3VP
-added misc. capacitors
PCB
-min. annular ring for vias set to 0.125 from 0.2

Use JLC7628 impedance values to get more options in color selection.
Also this leads to slightly wider traces typically, and it will be
easier to switch back to JLC2313 or the like than the other way around.
Also swap placing of HDMI/SW2 and rotate the heatsink by 90° for easier
routing.

Adjust some high level placement like M.2 or CM4 and heatsink. Remove
all traces and vias since most of the layouting has to be redone
anyways.

- Use Diodes B2100-13-F consistently
- Define part for pin headers
- Replace N-Channel MOSFET for PoE with BSZ440N10NS3GATMA1
- Define Input protection MOSFET DMP3013SFV-7

Remove power/reset/recovery switch. Power and reset is not really required
and recovery mode (USB Boot) can be triggered via jumper. Make the Fan
and RPiLED a new separate config so we can leave them unpopulated. Add a
second GPIO controlled switch.

Make sure those signals are well defined even when not be driven from
the CM4 side. Also rename Radio.BOOT to Radio.~BOOT since its a low
active signal.
Fixes: #10

Add the CM4 board to board connectors using separate symbols. This is a
bit a hack, but makes sure two pieces appear in the BOM.
Also, this seems to upgrade all the schematic to the latest KiCad
schematic version.

changes:
-more routing
-added poe negotiation disabled when +12V is present on the DC jack
-modified m.2 "holes"

Make sure property ids are unique within a symbol. This should avoid
that Manufacturer properties disappear in the future.
