Attempting to write EEPROM trashes flash

[GoogleCodeExporter]

optiboot does not support EEPROM, which is sort-of OK.  But in its thrift, it 
will interpret EEPROM write commands as writing to flash instead, overwriting 
code that might have been there.  That's not good!

possible diff.  Adds about 10 bytes.

If BIGBOOT or SUPPORT_EEPROM is set, actually support writing EEPROM (happens 
on 644, 1284, 1280 by default.)  This doesn't fit in 512 bytes, so Atmega328 
and etc will just error/timeout if an EEPROM write is attempted.
