* Be even more defensive around KoboUSBMS handling in the startup script And add some more logging. To the log before a session, to the syslog after, because we can't be sure onboard is viable. * Display a short version string straight in the Version label * Move system statistics inside the Help menu * Move Version inside Help * Bump base https://github.com/koreader/koreader-base/pull/1173
