Increased mini-USB plug drill hole size

Imported MINI-USB- device from Hirose Connectors library into kwoo
library. In UX60-MB-5S8 package, increased drill hole size on corner
pins from .8 mm to .9 mm. I did not drill out the original too-small
holes on Scoutfly, so I don't know whether this is sufficient or not....

Updated inductor package for power board

Created new package and device in library for MPI4040 inductor to be
used in power test board. Updated part on power test board.

Fixed GND pad on LT3650 charger IC

LT3650 package in kwoo.lbr had a polygon around a through-hole pad to
approximate a large SMD pad connected by a via directly to the ground
plane. Created a new package that is like this one but has no via, just a
normal SMD pad. Used this package in the power test board, which has no...

Updated design rules for power board

Updated design rules for power board to match DorkbotPDX specifications.
This removed some of the DRC errors for the USB port and charger. The
charger still has a couple that may be from inherently illogical
package specification.

Added new charger and pushbutton controller parts

Added LT3650 and LTC2954 to kwoo.lbr. Kevin sent me an updated library
with these parts previously, but I mistakenly did not import them at
that time.

Disapproved DRC errors on power board

Disapproved of previously approved DRC errors for power board. They are
apparently legitimate problems that need to be taken care of.

powerboard placed, needs routing

Fixed gas gauge and charging components

Added extra decoupling capacitor between battery voltage and ground next
to charging circuit to allow board to run with charger but no battery.
Connected system side of gas gauge sense resistor to GND to make all
current returning to battery go through sense resistor. Removed 0 Ohm...

Added missing components around AVR on power board

Added ISP header, pullup resistor for AVR reset line, and decoupling
capacitors for AVR power lines. Connected ISP header to SPI interface on
AVR.

Finished USB interface on power board

Added decoupling capacitors to FTDI chip, changed signaling VCC from USB
VCC to AVR VCC so that AVR can signal to FTDI chip. Added USBTX and
USBRX signals between FTDI chip and AVR.
