The LATEST variable in eeprom and ram is not correctly
initialized. EMPTY fixes that if everything is done correctly.

After programming the chip, the first 2 bytes of eeprom must contain 
0xffff in order to trigger correct initialization of the eeprom.
That can be achieved by letting the ICSP programmer erase the chip 
before programming it.
