Widened traces, moved gas gauge power supply

Widened traces that carry VBATT. Lined up decoupling capacitors for LDOs
with their connected LDO ports. Rerouted various traces ripped up during
execution of previous changes.

Rerouted decoupling caps and pullup around AVR

Rerouted decoupling capacitors and new pullup resistor around AVR to
increase trace width for power inputs and decrease unneccessary loops.

Fixed USB circuit problems

Routed USB_TX and USB_RX more directly. Put decoupling capacitors on FTDI
chips closer to the inputs they decouple.

Changed center ground pad for DS2786 and LT3650

Changed ground pads for packages 10MSOP and 12TDFN to have through-hole
pads on the bottom instead of SMD pads. Updated power test board to use
the new DS2786. Drew a polygon of BATT_GND around center pad. Not sure...

Updated power test schematic

Based on feedback from Kevin, added a pullup resistor to !PWR_INT and
decoupling caps to the LDO providing VCC.

Also changed the ground signal on the gas gauge LDO from GND to
BATT_GND. Kevin pointed out that having BATT_GND as the ground for the...

Minimized possible inductive loop in power board

Moved trace driving FAULTLED to minimize area of inductive loop in
vicinity of charger.

Finished power board routing (first attempt)

Routed all signals on power test board. There are no airwires, and the
board passes DRC. I believe I have kept the inductive loops near the
charger pretty small, but they could probably be improved. I also made...

Partially routed charger on power test board

Routed some of the signals connected to the charger IC on the power test
board.

Routed gas gauge on power board

Routed signals attached to fuel gauge on power board.

Started to route LDO signals

Started routing the signals attached to one of the LDOs.
