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
