Changed USB port drill holes back to spec

Looked at mini USB port with Dan. Observed that corner drill holes are
supposed to be multiple drills right next to eachother. Decided to
change holes back to specfied radius and ignore long hole for now.

Updated DS2786 footprint in kwoo library

Updated package footprint for DS2786 in kwoo.lbr based on recommended
land placement in datasheet for DFN10 package. DS2786's datasheet lists
TDFN10 as its package type but doesn't give placement guidance or a
useful package description. Unable to find a datasheet for TDFN10, but...

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 kwoo.lbr with previous kwoo changes

A few months ago, Kevin sent me a new version of kwoo.lbr. Updated
kwoo.lbr with these changes (using the Eagle update command). Also ran
update in scoutfly.sch. This did not affect the results of erc or drc
for scoutfly.

Finished hooking up new gyroscope.

Connected pitch output of gyroscope to AVR and gave pitch an output LPF.
Added optional HPFs to both pitch and yaw outputs. We can just leave the
pads empty if we think they won't be useful.

To route the changes, had to squeeze some other stuff. Moved the AVR...

Swapped gyroscope part in schematic.

Replaced old gyroscope part with new one in schematic. Assuming that
pitch output or amplified outputs are undesired. Not using optional
high-pass filter on output. Have not yet routed connections to gyroscope
on board.

Began fixing bugs for Scoutfly fixup.

Made several of the changes listed on wiki page ScoutflyUpdate2011. In
particular:
Removed R4 and connected pin 4 on U$3 directly to VCC.
Connected VREG_EN to VCC with 10 kOhm resistor (new R4).
Changed value of R26 to 100 kOhms....
