- Add "debug" target. It is still somewhat shaky, you need to "make clean" before "make debug", and it does not do much besides writing a few debug lines during the boot sequence. - Add a hard coded version number which is no longer a part of the strings file (and does not need to be translated). - Using a Cyclops iEvolution no longer triggers Slot 2 mode. - Fix doing multiple things in FTP mode without having to restart.
