* rename Argus leds to avoid underscores
* rename Belkin F5D8235 v1 leds from f5d8234 to f5d8235
* remove Belkin F5D8235 v1 status led defined as storage led (it was
  defined as usb led earlier, just in wrong place) - it should have
  router led as in v2

* add Belkin F5D8235 v1 and v2 usb leds
* fix Belkin F5D8235 v2 network config generation and mac address axtraction
* fix Sparklan board identification
* add Sparklan usb led (this board doesn't have usb connector by
  default and the led is hidden also but if you are going to solder
  the connector then you'll see the led too)
* add Sparklan network config generation and mac address extraction
* fix empty string test in network script and...
* ...sort case entries by the first board in the list
