WestfW 6f7687b0f9 Shrink code by using registers for variables "length" and "address"
http://code.google.com/p/optiboot/issues/detail?id=33

Fix high-value watchdog timeouts on ATmega8
http://code.google.com/p/optiboot/issues/detail?id=38

Change "start app on bad commands" code to start the app via the
watchdog timer, so that the app is always started with the chip
in fully reset state.
