Subject: slugos-init: update for new LEDs, turnup save/restore suppport in
 0.10  - /sbin/leds is now a script which uses /sys/class/leds    All scripts
 are not in /sbin    /sbin/sysconf does SysConf reading and now implements
 save/restore    of the system configuration.    turnup, reflash and
 sysconfsetup use /sbin/sysconf as appropriate    Unused files removed
