altosui: Capture config and version info in .eeprom files

Instead of only writing the serial number to the .eeprom file, write
all of the config values and all of the version reply to the .eeprom
file. The config values, in particular, contain the accelerometer
calibration data which is needed to correctly compute acceleration
from the captured accelerometer data.
