 * Settings and EEPROM storage
 *
 * IMPORTANT:  Whenever there are changes made to the variables stored in EEPROM
 * in the functions below, also increment the version number. This makes sure that
 * the default values are used whenever there is a change to the data, to prevent
 * wrong data being written to the variables.
 *
 * ALSO: Variables in the Store and Retrieve sections must be in the same order.
 *       If a feature is disabled, some data must still be written that, when read,
 *       either sets a Sane Default, or results in No Change to the existing value.
