Changed how the eye calibration handles infrared noise (aka the sun) to be
more flexible.
Changed personality modules detection to the setup phase instead of
continuously checking.
Fixed a bug init the Touchy-Feely init not setting the pin input mode
correctly.
Expanded the update method in the firmware instead of in the library. This
should make it easier to tweak the firmware.
