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
