renamed s/shield-adapter/galago-shield-adapter/ for consistency
updated all board firmware to version 2 to fix a subtle bug. v1 firmware was only deployed on some Etherblock boards where it had no effect anyway. Added IO::SPI::lock()/unlock() methods, fixed interrupt insulation with InterruptFreeEnter()/Leave() and a lot of other bugs that appeared in testing. Also added working, tested modules for nearly all the App Boards and updated the logiblock/app-board driver too.
