Shorted GND to BATT_GND in power schematic

Connected GND and BATT_GND to eachother using a 0 Ohm resistor. I want
to keep the signals separate to ease routing, but they need to be
connected to ensure that all of the current that needs to go through the
fuel gauge sense resistor does so.

Fixed ERC errors

Added some missing junctions and a missing label. Approved "no value"
warnings for parts for which a value would be nonsensical.

Started making kwoo's recommended changes

Made changes to charging circuit: Connected CLP to VIN on U1. Added
diodes to charge BOOST capacitor from battery and provide current
sensing inductor with outlet if power turns off (don't really understand
how the latter works). Adjusted inductor to 4.7uH after re-calculating...

Update prefixes and names for two parts

Updated prefixes for DS2786 and MP1702 in kwoo.lbr to U so that Eagle
won't use the default prefix, U$, for them. Also manually updated names
in charging_test.{sch,brd}.

Added pullup resistors and an LED to power test

Added pullup resistors for I2C connections to power test board. Also
added a diagnostic LED to indicate when the AVR has power. Still
probably needs an ISP header and USB controller/port.

First draft of power testing circuit schematic

Fleshed out power testing circuit. It is still missing a few things, and
I don't understand every little bit of it, but it probably won't look a
lot different when it's done. Added some passive components on the...

Updated charging test circuit from kwoo library

Ran update command in charging_test.sch to update parts from kwoo.lbr.

Added kwoo's standalone charging schematic.

charging_test.sch is a standalone circuit schematic for a prototype to
test the charging circuit that will ultimately go on Scoutfly. kwoo
created it. It uses some new parts, but I don't know that much about it...
