EEPROM position storage, more ser command updating

The current position, end limit, program start position, and program
stop position can now be stored to EEPROM.

All function calls are now included in the updated
OM_Serial_Com_Client.ino

The function powerCycled() can now be called from a serial command to
report whether the controller has been powered down since the last
query.

A few fixes to the command spread sheet have also been made.
